Core Features

Everything you need to identify, grade, and organize the coins in your hands.

📸

Instant Coin Identification

Point your camera at a coin and Coinzo identifies the country, denomination, year, and mint mark in seconds — no typing required. Works on both the obverse and reverse.

🏅

AI Grading Estimate

Coinzo evaluates wear, luster, strike, and surface to estimate a grade on the Sheldon 1–70 scale — for example VF-20, AU-50, or MS-63 — so you have a starting point before professional grading.
