How Does AI Coin Grading Work?
Our proprietary AI model analyzes your coin photos against a database of thousands of reference images from professionally graded coins. It examines wear patterns, surface conditions, strike quality, and eye appeal to provide a grade estimate based on the 70-point Sheldon scale—the same standard used by PCGS and NGC. While not a replacement for official certification, CoinSensei gives you reliable estimates for personal collection management and helps you decide which coins are worth sending for professional grading.
