Stop paying to grade coins that won't pay you back
Photograph a lot, get a Sheldon-scale estimate on every coin, and send only the ones where the premium clears the fee. Each estimate takes under 10 seconds.
Free tier, no card. Paid plans to $399/mo when volume needs them.
AI coin grading software estimates Sheldon-scale grades from photographs at volume, so a dealer can triage inventory before paying submission fees. CoinGrader AI returns each estimate in under 10 seconds, lands within 2 points of the PCGS grade 95% of the time, and offers API access on plans from free to $399 a month.
What it does at volume
One coin is a question. Four hundred coins is a workflow, and the problem changes shape — consistency matters more than any single answer.
Triages a lot into three piles
Submit, hold, reject. The only three decisions that exist.
Runs through an API
Push images from your own inventory system and read grades back.
Applies one standard
The model doesn't get tired at coin 300, or generous about its own stock.
Flags Details risk early
Cleaning and damage caught before the fee is spent, not after.
Informs the tier choice
Estimated grade drives estimated value, which drives which tier you qualify for.
Needs no install
Browser-based on any machine. Nothing to deploy, nothing to license per seat.
Against how it's done now
Most inventory gets triaged one of two ways: someone experienced eyeballs it, or everything goes in the box and the fees sort it out.
| Approach | Cost per 50 coins | Time | Consistency |
|---|---|---|---|
| Submit everything | $1,100 | 5–65 days | Perfect, and expensive |
| Eyeball the lot | $0 | Hours | Depends who's looking |
| Send to a dealer friend | $0 | Days | Their interest, not yours |
| CoinGrader AIThis | $0–$399/mo | Under 10 sec each | Same standard every coin |
The $1,100 assumes 50 coins at PCGS Economy's $22, before handling or shipping. Real per-coin fees vary by service and declared value — see PCGS grading fees, NGC grading fees and ANACS grading fees for the current tier tables.
How a lot moves through it
- Shoot the inventory. Both sides, diffuse light, dark background. A copy stand pays for itself at volume.
- Upload or push via API. Batch through the interface, or wire it into whatever holds your stock.
- Read the triage. Each coin gets a grade, a confidence, and a submit-or-skip call.
- Send the shortlist. Declared values follow the estimates, which is also what picks your tier.
The packing and paperwork end is unchanged — the step-by-step submission walkthrough covers it, and the mechanics are much the same across services.
What it costs
Plans start free and run to $399 a month at the top. The free tier is a real tier, not a trial with a clock on it. Volume is what moves you up, so a dealer running a few hundred coins a month sits somewhere in the middle and a collector never leaves the bottom.
Set that against one avoided submission. A single coin held back at PCGS Economy saves $22 before shipping. Thirty-seven of them saves $814.
It doesn't replace certification
No holder, no guarantee, no effect on what a buyer pays. Only PCGS, NGC, PSA and ANACS issue grades the market prices against, and nothing here changes that. The software decides which coins earn a submission — it doesn't substitute for one.
There's no lock-in either. Nothing to install, no data migration, no contract. If it stops earning its place, you stop uploading.
Who it's wrong for
Dealers whose inventory is already certified, anyone needing insurance or probate valuations, and operations that can't photograph consistently. Grading reads surfaces, and surfaces read badly under a single hard light. Bad photography in, soft grades out.
It's also the wrong tool for a single coin. If that's the job, the free grading app does it in a browser with no account at all.
FAQ
What is AI coin grading software?
Software that estimates a coin's Sheldon-scale grade from photographs, at volume. It's used to decide which coins in a lot justify professional submission fees, rather than to certify anything itself.
Is there an API?
Yes. You can push images from your own inventory system and read grades, confidence scores and submit recommendations back. That's the usual setup once a dealer is past a few hundred coins a month.
How much does it cost for a dealer?
Plans run from free to $399 a month, scaling with volume rather than seats. One avoided PCGS Economy submission saves $22 before shipping, so the arithmetic turns over quickly at any real scale.
Does accuracy hold up at volume?
The model applies the same standard to coin 400 as to coin 1 — estimates land within ±2 points of the PCGS grade 95% of the time. Photo consistency is the variable that matters, which is why a copy stand helps.
Can it replace sending coins to PCGS or NGC?
No. There's no holder and no guarantee, and buyers pay premiums for certification rather than estimates. It changes which coins you send, not whether you send any.
Can it handle bulk uploads?
Yes, through the interface or the API. A lot comes back as a triage list — submit, hold, reject — with a grade and a confidence against each coin.
What do I need to install?
Nothing. It's browser-based, so there's no desktop client, no per-seat licence and no deployment. Any machine that can open a web page can run it.
Triage the lot before you pay for it
Upload a batch and see which coins clear the fee at their likely grade. Free tier, no card, nothing to install.
