Our Story

Your First Step in Coin Evaluation

We help collectors identify what they have, estimate what it's worth, and make informed decisions about whether professional grading is worth the investment.

Know Before You Grade

Professional coin grading from PCGS or NGC costs $30-150+ per coin, with wait times of weeks or months. That investment makes sense for valuable coins—but how do you know which coins are worth it?

coingrader.app helps you answer that question. Using AI analysis, we help you identify what you have, estimate what it might be worth, and decide whether professional grading makes financial sense.

We're not a replacement for professional grading services. PCGS and NGC provide certified, market-accepted grades essential for selling valuable coins. We're a screening tool that helps you make smarter decisions about which coins deserve that investment.

Think of us like a home inspection before buying a house—helpful guidance before you commit, not a replacement for professional appraisals.

How Our AI Analysis Works

Our AI analyzes your coin photos to provide preliminary assessments. We examine wear patterns, surface conditions, and details to give you an estimated grade range and value—helping you decide if professional certification is worthwhile.

Condition Assessment

Evaluate wear, surface quality, and problems to estimate a grade range (not a certified grade).
