AI coin identifier & value estimatorKnow your coins.
Scan any coin — front and back — and get an instant AI identification, honest value estimates, and a treasure collection that grows with every find.
Product
More than a scanner — a treasure hunt.
Coin Sense turns loose change into a discovery. Identify, estimate, and build a collection that grows with every find.
Two-sided AI scan
Photograph the obverse and reverse of any coin and get likely matches in seconds, with confidence scores for each result.
Honest value estimates
See realistic low/likely/high value ranges with a confidence score — never fake precision where there isn't any.
Treasure collection
Save your finds, build themed sets, and watch your total treasure value grow with every discovery.
Chat with Penny
Ask Penny, your AI numismatist, about rarity, mint marks, grading, or what to photograph next.
Explore encyclopedia
Browse thousands of coins with photos, historical context, mintages, and pricing references.
Honest & private
Collection stored on-device; photos processed for ID and not retained. Confidence, not false certainty.
Flow
From loose change to a saved discovery.
Three quick steps: scan both sides, get an honest estimate, then save the find to your growing treasure collection.

Photograph the front and back of any coin in even lighting for the best match.
Estimate
Review the top match, confidence score, and an honest value range for your coin.
Collect

Guide
Meet Penny, your treasure companion.
Penny is a small treasure-mouse who celebrates every find and keeps the app honest about what it knows and what it doesn't. Value estimates are ranges, not certainties — Penny will always tell you when to check with a professional.
