Error Hunter is the world's first AI-powered coin and currency error detection platform. We help collectors, dealers, and hobbyists discover valuable minting errors in their pocket change and collections — instantly.
Every scan runs through three independent AI engines — local ML, Ximilar Collectibles, and GPT-4 Vision — for the most accurate error detection possible.
Simply take a photo of any coin or bill. Our AI analyzes it in seconds and tells you if it contains a valuable minting error and what it might be worth.
The only coin scanner with built-in weight verification. Compare your coin's weight against official mint specs to confirm wrong planchet and transitional errors.
Detect errors on coins and currency from the US, Canada, UK, Eurozone, Australia, and more. Our models cover all major world mints.
For paper currency, we detect fancy serial numbers — radars, ladders, solids, low serials, star notes, and more — with instant rarity scoring.
Your scans are private and secure. We use enterprise-grade encryption and never share your data. Trusted by collectors worldwide.
Your first 3 scans are free. No credit card required.
