Coin Scanner
Scan the front and back of any coin with your camera. Coin Sense reads the visible clues and returns confidence-scored matches — plus a clear next step when a find deserves a closer look.
Why use Coin Sense as your coin scanner?
Coin Sense is built for quick photo-based identification, but it stays honest: every result is an educational first guess with confidence and clear next steps — never a fabricated value.
Obverse + reverse scan
Photograph both sides for a fuller picture — mint marks and design details on the back often matter.
Confidence-scored matches
Every scan returns low, medium, or high confidence — never false certainty about what you found.
Collectible discovery
Get flagged when a coin's visible features resemble a known collectible variety, with a clear next-check list.
Identify common coins faster
Start with a photo, then use denomination, mint mark, date, and simple weight/diameter checks to narrow down the result.

Coin scanner FAQ
What's the difference between a coin scanner and a coin identifier?+
They're closely related. A 'scanner' emphasizes the camera-first workflow — obverse, then reverse — while an 'identifier' emphasizes the result. Coin Sense combines both: scan both sides, get an identified, confidence-scored result.
Does the scanner work on worn or dirty coins?+
It can still return a result, but confidence drops as key details (date, mint mark, design) become harder to read. Gently wipe off loose dust — never clean or polish a coin, which can reduce its value.
Can I scan foreign coins?+
Yes. Coin Sense attempts identification for US and world coins, though confidence is often lower for less common or historical issues.
How many scans do I get for free?+
One free web scan per day. Download the app for unlimited two-sided scans and a saved collection.
Coin Sense is an educational app. AI photo identification and value ranges can be a helpful first step, but they are not a certified numismatic appraisal, a guaranteed grade, or a real-time auction price. Verify valuable, damaged, or potentially rare coins with a qualified professional numismatist.
