Snap any coin — identify it, grade it, and see what it's worth in seconds. From wheat pennies to ancient coins, Coin AI does the homework for you.
Coin AI is the fastest way to identify a coin, check its value, and grade its condition — all from your phone. Snap the obverse and reverse, and our vision AI scans both sides together to recognize US coins, world coins, ancient and rare coins, and known mint errors — then estimates a market price range based on current collector data. Whether you found it in pocket change, inherited a collection, or pulled it from a flea-market jar, you'll know exactly what you have in seconds.
WHY COIN AI IS DIFFERENT
No cluttered feeds. No paywalled magazine articles. Coin AI is laser-focused on one thing: telling you what a coin is and what it is worth, fast.
IDENTIFY WITH BOTH SIDES
Capture the obverse (front) and reverse (back) of your coin. Coin AI analyzes both images together for maximum identification accuracy — something most coin scanner apps skip entirely.
AI-POWERED GRADING
Get detailed condition grading with surface quality, luster, and strike analysis. Each scan includes a confidence score so you know how reliable the result is.
INSTANT VALUE ESTIMATES
See estimated market price ranges (low to high) based on current collector data. Know whether your coin is worth $5 or $5,000 before you visit a dealer.
VISUAL GRADING CARDS
Beautiful, shareable grading cards display your coin details at a glance — grade, condition notes, rarity, historical context, and value range.
COLLECTION VAULT
Build and organize your personal coin collection digitally. Every scan is saved with full identification details and images.
WHAT YOU CAN IDENTIFY
- US coins: wheat penny, Lincoln cent, buffalo nickel, Mercury dime, Roosevelt dime, Washington quarter, commemorative quarter, Kennedy half, Morgan dollar, silver dollar, peace dollar, proof set
- World coins from 190+ countries and territories
- Ancient, historical, and error coins (mint mark varieties, off-center strikes, doubled dies)
- Commemorative, proof, and bullion coins (gold, silver, platinum)
WHY NUMISMATISTS USE COIN AI
Coin AI works alongside the references serious collectors already use — PCGS CoinFacts, NGC Coin Explorer, Greysheet Pricing — by giving you a fast first-pass identification before you spend on professional grading. Treat each scan as a starting point and confirm rare or high-value finds with a certified grader.
PERFECT FOR
- Casual collectors discovering coins in pocket change
- Inherited collections that need identification and appraisal
- Estate sale, flea market, and antique shop finds
- Serious numismatists wanting a quick AI-powered reference
Coin AI is built by collectors, for collectors. Fast, accurate coin identification, grading, and value estimates — exactly what you need.
