Coinaikon: AI Coin Identifier

Scan, Identify, Grade, and Manage coins instantly.

Coinaikon is the ultimate companion for coin collectors and numismatists. Identify, grade, and value your US coins instantly — snap a photo or search by name, year, and mint mark. Get professional results in seconds, not days.

IDENTIFY ANY US COIN
Point your camera at any US-minted coin from 1793 to present — pennies, nickels, dimes, quarters, half dollars, and dollar coins. Our AI instantly recognizes the coin, flags potential key dates and rare varieties, and returns detailed historical context.

AI-POWERED GRADING
Receive a professional-grade condition assessment backed by machine learning trained on thousands of certified coins, achieving 95%+ accuracy. Review the AI's preliminary grade, then override it with your own assessment whenever you prefer. The human is always in control.

MARKET-INFORMED PRICING
Know what your coins are worth. Coinaikon provides price estimates derived from recent market trends and publicly available resources, giving you a reliable starting point for buying, selling, or insuring your collection. You can also add your own custom valuations based on local markets or personal expertise for true hybrid intelligence.

COLLECTION MANAGEMENT
Organize your entire portfolio in one place. Track value over time, categorize by series or set, and monitor your collection's performance with advanced analytics and portfolio charts. Import existing collections from CSV or spreadsheet — no need to start from scratch.

SYNCED EVERYWHERE
Your collection is never trapped on a single device. Coinaikon works seamlessly as a web app and a mobile companion. Organize at your desk, scan coins on the go at a coin show — everything stays perfectly synchronized.

BUILT BY COLLECTORS, FOR COLLECTORS
We understand the joy of holding history in your hands. Coinaikon puts you in control: AI handles the heavy lifting so you can focus on the thrill of the hunt and the stories behind every strike.
