Written by Acorn Sales Company, manufacturing stamps and seals since 1964 · Reviewed by Holly R, VP of Sales and Marketing at Acorn Sales, against Acorn Sales product catalog, loyalty-reward-stamps range on 21 September 2026 · Updated 25 September 2026
Acorn publishes 501 reward stamps, and the reward they are built for is a student’s, not a coffee card’s. Nearly every one imprints at Small 1/2″ x 1-1/2″ or Large 3/4″ x 2-1/4″, and the mount sets the price: a Shiny Duo hand stamp is $12.95 and needs its own pad, a Trodat self-inker is $15.95 with 11 ink colors and up to 10,000 impressions, a wood handle stamp is $15.95, and a Slim or PSI pre-inked stamp is $16.95 with 5 ink colors and up to 25,000 impressions on the Slim or 15,000 on the PSI.What these are for
A reward stamp replaces the sentence a teacher writes forty times a day, and gives a child something visible to collect. Our catalog builds the range around four jobs. Praise for the work: Smart Cookie, Bravocado, Totally Radical, Muscle-Tastic Job, You’re So Sharp, Quack-Tastic Work, Bear-Y Good Work. Praise for the process rather than the answer: Show Your Steps, Excellent Explanation, Progress Over Perfection, Math-Tastic Thinking, Graph Genius, Scientifically Impressive. Behavior and routine: Calm And Ready, Transition Champ, Waited Your Turn, Respected Personal Space, Teamwork, Stayed Organized. Revision prompts that still read as encouragement: Needs More Time, Missing Something Can You Spot It, Not Done Yet, Check Yo Work, Started Strong Stopped. The buyers our pages name are elementary classroom teachers, homeschool parents, after-school program coordinators, classroom aides and special education staff, tutors and resource-room teachers. A named gap worth stating: our catalog does not publish a customer loyalty punch card or buy-ten-get-one stamp family in this range. If that is what you are looking for, it is not in these 501 SKUs.
The ranges we stock
Shiny Duo hand stamp, $12.95, ink pad sold separately
The lowest price in the range and one of its largest families. The Teacher Reward Organized And Prepared Hand Stamp, the Classroom Reward Totally Radical Hand Stamp, the Teacher Reward Check Yo Work Hand Stamp and the Classroom Reward Infinite Potential Hand Stamp are each $12.95. The Duo is a modular body that snaps together for use and breaks down for storage, with a snap-on dust cover and an ergonomically molded handle our pages describe as treated with a fungistatic or antimicrobial agent, which matters in a room where thirty children touch the same tool. Inside is a precision laser-cut rubber die our pages say works with permanent and water-soluble inks, or industrial and water-based depending on the listing. Ink pad sold separately, which is exactly why it is the cheapest.
Trodat self-inking stamp, $15.95, 11 ink colors, up to 10,000 impressions
The Classroom Reward Smart Cookie Self-Inking Stamp, the Teacher Reward Chameleon Self-Inking Stamp, the Classroom Reward Scientifically Impressive Self-Inking Stamp and the Classroom Reward Missing Something Can Spot Self-Inking Stamp are each $15.95. Our pages call it Easy Press and Print: one press, ink carried inside on a pad. This is the only reward mount that offers the full 11 ink colors Acorn stocks, rated at up to 10,000 impressions, with case colors in Light Pink, Purple, Midnight Black and Fuchsia.
Slim compact pre-inked stamp, $16.95, 5 ink colors, up to 25,000 impressions
The Teacher Reward Progress Over Perfection Compact Pre-Inked Stamp, the Classroom Reward Calm And Ready Compact Pre-Inked Stamp, the Teacher Reward Bravocado Compact Pre-Inked Stamp and the Classroom Reward Transition Champ Compact Pre-Inked Stamp are each $16.95. Flat, light and built to live in a lanyard pouch, a planner pocket or a tote, which is what our pages sell it on for a teacher who grades on her feet. Ink is built in, oil-based, quick-drying and smudge-resistant, rated at up to 25,000 impressions. Colors are named explicitly: red, blue, green, purple and black.
PSI pre-inked stamp, $16.95, quiet action, up to 15,000 impressions
The Classroom Reward Show Your Steps PSI Pre-Inked Stamp, the Classroom Reward Be-Leaf In You PSI Pre-Inked Stamp, the Teacher Reward Math-Tastic Thinking PSI Pre-Inked Stamp and the Classroom Reward Work Is Magnetic PSI Pre-Inked Stamp are each $16.95. Same 5 ink colors as the Slim, fed from an internal oil-based reservoir, and rated at up to 15,000 impressions where the Slim gives up to 25,000. The difference our pages press on is noise: whisper-quiet, near-silent action named for testing time, independent reading, small-group instruction, libraries and sensory-sensitive rooms. One PSI page adds a feature no other stamp in the range has: the Classroom Reward Work Is Magnetic PSI Pre-Inked Stamp carries a built-in magnet so it parks on a whiteboard or a metal cabinet.
Wood handle stamp, $15.95, industrial inks, fabric and non-porous
The Classroom Reward Wheelie Your Work Wood Handle Stamp, the Classroom Reward Teacher Assisted Wood Handle Stamp, the Classroom Reward Needs More Time Wood Handle Stamp and the Teacher Reward Transition Champ Wood Handle Stamp are each $15.95. A laser-engraved rubber die under a black wooden handle, separate ink pad required. Our pages make two claims for it the sealed mounts never get: it avoids the wear and wobble of a self-inking mechanism because it has no internal moving parts, and it is the only reward mount written up for industrial inks on fabric and many non-porous surfaces, which is what puts a reward design on a spirit-day shirt, a class tote or a reward bag instead of a worksheet.
Designer and craft outliers, $26.95 and $32.95, 1-5/8″
Two products in this cluster are not classroom stamps at all and are priced accordingly. The Self-Inking God’s Loyalty Shines Bright stamp is $26.95, a 1-5/8″ square self-inking design carrying the message God is Faithful All the Time, rated at up to 10,000 impressions, bought by church administrators, pastors and Christian teachers for cards, journals, Bible study pages and church handouts. The PSI Scrapbooking Patience Brings Beautiful Rewards Pre-Inked Stamp is $32.95, also 1-5/8″, carrying Good Things Take Time in hand-drawn lettering with swirls and flourishes, rated at up to 15,000 impressions in 5 ink colors, bought by scrapbookers, memory keepers and card makers.
Sizes and dimensions
Two footprints cover almost the whole range, and they are the same on every stock mount: Small 1/2″ x 1-1/2″ and Large 3/4″ x 2-1/4″. That holds for the $12.95 Teacher Reward Organized And Prepared Hand Stamp, the $15.95 Classroom Reward Smart Cookie Self-Inking Stamp, the $15.95 Classroom Reward Wheelie Your Work Wood Handle Stamp, the $16.95 Teacher Reward Progress Over Perfection Compact Pre-Inked Stamp and the $16.95 Classroom Reward Show Your Steps PSI Pre-Inked Stamp alike. Our pages describe the choice the same way every time: small for margins, planner boxes, agendas, exit tickets and quick checks; large for worksheets, folders, behavior charts, posters and take-home sheets, where the mark should be readable from across a table. The exceptions are the two non-classroom products, the $26.95 Self-Inking God’s Loyalty Shines Bright stamp and the $32.95 PSI Scrapbooking Patience Brings Beautiful Rewards Pre-Inked Stamp, both of which imprint at 1-5/8″, a square image sized for a card front, a journal page or a gift tag.
How many impressions you get
Impression counts are published for the sealed mounts only, and the spread is worth knowing before you choose. The Slim and PSI pre-inked stamps at $16.95 are rated at up to 25,000 impressions and up to 15,000 respectively, the two highest figures in the range, which is why our pages call them the ones to buy if you stamp every paper every day. The Trodat self-inking stamps at $15.95 are rated at up to 10,000 impressions, and the $26.95 Self-Inking God’s Loyalty Shines Bright stamp carries the same 10,000 figure. The $32.95 PSI Scrapbooking Patience Brings Beautiful Rewards Pre-Inked Stamp carries the PSI 15,000. For the $12.95 Shiny Duo hand stamps and the $15.95 wood handle stamps, no impression count is published in our catalog, and that is the right answer rather than a missing one: neither carries ink, so the number belongs to the pad. One Duo page, the Teacher Reward Imagination At Work Hand Stamp, goes as far as saying it is made to endure hundreds of impressions, which is a durability claim about the die, not an ink figure.
Ink and colors
Three ink systems in one range. Self-inking: the $15.95 Trodat bodies offer the full 11 ink colors Acorn stocks, with case colors in Light Pink, Purple, Midnight Black and Fuchsia. Pre-inked: the $16.95 Slim and PSI bodies offer 5 colors, red, blue, green, purple and black, in oil-based ink our pages describe as fast-drying, smudge-resistant and fade-resistant. Pad-fed: the $12.95 Shiny Duo hand stamps and the $15.95 wood handle stamps carry no ink at all. Every one of those pages says ink pad sold separately and leaves both color and formula to you, which is why the wood handle listings are the only ones that talk about industrial inks for fabric and non-porous surfaces and the Duo listings name permanent and water-soluble options for different paper types and classroom policies. Acorn stocks 11 ink colors overall, so a 5-color pre-inked stamp is a restriction of that body, not of the shop.
What you can customize
This range is stock art with the message already engraved. What you choose is size, mount and ink, and nothing else, and our catalog publishes no character count and no line count for any stamp in it, because there is no text field to fill. That is deliberate rather than an omission: our pages sell the fixed message as the feature, on the grounds that a ready-to-use phrase removes the planning and keeps the wording consistent from the first paper to the last. If you want a teacher’s own name, a class or a school crest on a reward stamp, that is a custom order rather than a pick from this range, and Acorn’s standard artwork guidance applies: EPS is best and a transparent PNG is good, leave about 2% edge space around the imprint, and logo work is one color. Address-style lines run to no more than about 40 characters. There is no setup fee and no minimum order, and an optional PDF proof holds production until you approve it.
These are classroom reward stamps, not customer loyalty stamps.
The word reward pulls in two very different buyers, and only one of them is served by this range. Search for a loyalty stamp and you may be picturing a punch card: a tiny mark in a coffee-cup grid, ten stamps and the eleventh is free, a shop counter, a cardstock card in a wallet. Our catalog does not publish that family here. What these 501 SKUs are is classroom and teacher reward stamps, and almost every title in the range says so out loud: Teacher Reward and Classroom Reward.
Why it matters practically: the sizes are wrong for a punch card. Every stock stamp in this cluster imprints at 1/2″ x 1-1/2″ or 3/4″ x 2-1/4″, both of them wide rectangles built to carry a sentence such as PROGRESS OVER PERFECTION or TRANSITION CHAMP across a worksheet. A loyalty card grid wants a small square mark, and the only 1-5/8″ square products in this cluster are the $26.95 Self-Inking God’s Loyalty Shines Bright stamp and the $32.95 PSI Scrapbooking Patience Brings Beautiful Rewards Pre-Inked Stamp, neither of which is a punch mark either.
The second thing buyers get wrong sits inside the range itself. The four stock mounts are not a quality ladder from $12.95 to $16.95. They all carry the same kind of laser-cut die and imprint the same two sizes. What the money buys is where the ink lives. The $12.95 Shiny Duo and the $15.95 wood handle carry none, so you pick the color and the formula, you change color in seconds by changing pads, and the wood handle is the only one our pages write up for industrial inks on fabric and non-porous surfaces. The $15.95 self-inker carries one color inside and gives you speed and a clean desk while you circulate. The $16.95 pre-inked carries the most ink, up to 25,000 impressions on the Slim and 15,000 on the PSI, and the PSI version is the quiet one for a testing room.
The useful rule: if you grade at a desk and want a color-coded system across groups or subjects, buy a wood handle and three pads. If you grade on your feet, buy a Slim. If you stamp during testing or independent reading, buy a PSI. If you already own pads and want the lowest price, the $12.95 Duo is the same die in a modular body with a dust cover. And if you actually wanted a punch card stamp, ask for a custom one rather than picking from this range.
Ordering, proofs and delivery
Production is 1 business day. Orders ship from Richmond, Virginia, with transit of 3 to 10 business days depending on method and carrier, sometimes next day with rush shipping selected. There is no minimum order and no setup fee, so a single $12.95 hand stamp is a perfectly ordinary order, and so is a grade-level set bought on a department budget. A PDF proof is an optional add-on; production waits on your approval when you add one, which matters on custom artwork rather than on a stock design. Two practical ordering notes. The $12.95 Shiny Duo hand stamps and the $15.95 wood handle stamps arrive with no ink, so add a pad to the same cart if you do not already keep them. And size is a separate product rather than a later option, so decide between Small 1/2″ x 1-1/2″ and Large 3/4″ x 2-1/4″ against the paper you actually grade on before you check out.
Care and longevity
It depends on which mount you bought. A Slim or PSI pre-inked stamp at $16.95 runs up to 25,000 impressions on the Slim and up to 15,000 on the PSI. A Shiny Duo at $12.95 has almost nothing to maintain: keep the snap-on dust cover over the die between rounds, which our pages say is what stops lint and stray ink from degrading the image in a desk drawer, a teacher tote or a rolling cart. The modular body also breaks down for storage. A wood handle stamp at $15.95 has no internal moving parts, which our catalog frames as fewer failures than a self-inking body; wipe the die after any industrial, pigment or permanent ink and store it face up. Acorn warrants rubber stamps for six months, which is the term printed on our product pages. That is the warranty, not the expected life: in normal use a stamp body lasts several years, and the part that wears first is the pad or the ink rather than the die.

Frequently asked questions
Are these stamps for customer loyalty cards or for classrooms?
Classrooms. All 501 published SKUs in this range are teacher and classroom reward stamps, with titles that begin Teacher Reward or Classroom Reward. Our catalog does not publish a customer loyalty punch card stamp family here, and the two stock sizes, 1/2″ x 1-1/2″ and 3/4″ x 2-1/4″, are wide rectangles built for a sentence, not a small square for a punch grid. A punch card mark would be a custom order.
How many reward stamp designs does Acorn publish?
501 published SKUs. That counts mounts and sizes separately: most messages appear as a $12.95 hand stamp, a $15.95 self-inker, a $15.95 wood handle stamp and a $16.95 pre-inked stamp, each in Small and Large, so the number of distinct messages is a good deal smaller than 501. The messages cover praise, process, behavior and revision prompts.
What is the cheapest reward stamp, and what is the catch?
The $12.95 Shiny Duo hand stamp. The catch is stated on every one of those pages: the ink pad is sold separately. You are buying a modular body with a snap-on dust cover, a fungistatic handle and a precision laser-cut rubber die, and supplying the ink yourself. If you already keep pads, it is the same die as the more expensive mounts for four dollars less. If you do not, add a pad and the gap closes.
How many impressions will a reward stamp give me?
Up to 25,000 from a Slim pre-inked stamp at $16.95, up to 15,000 from a PSI pre-inked stamp at $16.95, and up to 10,000 from a Trodat self-inking stamp at $15.95. No count is published for the $12.95 Shiny Duo hand stamps or the $15.95 wood handle stamps, because they carry no ink of their own; their life is set by the pad you pair with them.
How many ink colors can I choose from?
It depends on the mount, and this trips people up. The Trodat self-inking stamps at $15.95 offer 11 ink colors, the full set Acorn stocks, plus case colors in Light Pink, Purple, Midnight Black and Fuchsia. The Slim and PSI pre-inked stamps at $16.95 offer 5: red, blue, green, purple and black. The $12.95 Shiny Duo and the $15.95 wood handle stamps offer whatever pad you buy. If a color-coded system across groups or subjects matters, that difference is worth more than the price gap.
Which reward stamp is quiet enough to use during a test?
The PSI pre-inked stamps at $16.95. Every PSI page in this range leads on noise, describing whisper-quiet, near-silent action and naming testing time, independent reading, small-group instruction, libraries and sensory-sensitive rooms as the reason. The Classroom Reward Show Your Steps PSI Pre-Inked Stamp and the Classroom Reward Be-Leaf In You PSI Pre-Inked Stamp both carry that claim, and both are rated at up to 15,000 impressions.
Can I stamp a reward design on a tote bag or a class shirt?
With the $15.95 wood handle stamp, yes. It is the only reward mount our catalog writes up for industrial inks on fabric and many non-porous surfaces. The Classroom Reward Wheelie Your Work Wood Handle Stamp and the Classroom Reward Teacher Assisted Wood Handle Stamp both state it, and the Teacher Reward Transition Champ Wood Handle Stamp adds the sensible caution to test the ink first. The sealed $15.95 and $16.95 bodies are written up for paper: worksheets, folders, planners, reading logs and behavior charts.
What sizes do reward stamps come in?
Two, on every stock mount: Small 1/2″ x 1-1/2″ and Large 3/4″ x 2-1/4″. Small is for margins, planners, agendas, exit tickets and quick checks. Large is for worksheets, folders, posters, behavior charts and take-home sheets. The only 1-5/8″ items in this cluster are the $26.95 Self-Inking God’s Loyalty Shines Bright stamp and the $32.95 PSI Scrapbooking Patience Brings Beautiful Rewards Pre-Inked Stamp, which are card and journal designs rather than grading marks.
Can I get my own name or my school on a reward stamp?
Not from this range. Every one of these 501 SKUs arrives with its message already engraved, which is why our catalog publishes no character count and no line count for them. Custom wording or a school crest is a separate custom order with no setup fee and no minimum. For artwork, EPS is best and a transparent PNG is good, leave about 2% edge space around the imprint, and logo work is one color. Add the optional PDF proof so nothing is produced until you have seen it.
What is a Shiny Duo?
The modular hand stamp body behind the $12.95 reward stamps. It snaps together for use and breaks down for storage, comes with a snap-on dust cover that protects the die in a desk drawer or a teacher tote, and has an ergonomically molded handle our pages describe as treated with a fungistatic or antimicrobial agent for shared classroom use. Inside is a precision laser-cut rubber die that works with permanent and water-soluble inks. Ink pad sold separately.
Is there a reward stamp that stays on the whiteboard?
One. The Classroom Reward Work Is Magnetic PSI Pre-Inked Stamp at $16.95 has a built-in magnet so it parks on a whiteboard or a metal cabinet and stays within reach during instruction and small-group rotations. It is the only stamp in this range our catalog describes that way, and it carries the standard PSI specification otherwise: 5 ink colors, up to 15,000 impressions, quiet press, both stock sizes.
Why are two stamps in this range $26.95 and $32.95?
Because they are not classroom stamps. The $26.95 Self-Inking God’s Loyalty Shines Bright stamp is a 1-5/8″ square faith design reading God is Faithful All the Time, rated at up to 10,000 impressions, bought for cards, journals, Bible study pages and church handouts. The $32.95 PSI Scrapbooking Patience Brings Beautiful Rewards Pre-Inked Stamp is a 1-5/8″ craft sentiment reading Good Things Take Time, rated at up to 15,000 impressions in 5 ink colors, bought by scrapbookers and card makers. Both are larger square images for a card front, not rectangles for a worksheet.
How fast will a reward stamp arrive?
Production is 1 business day and orders leave Richmond, Virginia. Transit is 3 to 10 business days by method and carrier, sometimes next day if you select rush shipping. There is no minimum order and no setup fee. If you add the optional PDF proof on a custom order, production waits until you approve it, so allow for that ahead of back-to-school or a testing week.
