Frequently Asked Questions

Are all of these tools really free?
Yes. Every tool on this page is free to use with no sign-up, subscription, or hidden fees. The site is supported through affiliate partnerships with eBay, Amazon, and precious metals dealers rather than tool access fees.

How accurate is the Error Coin Identifier?
The Error Coin Identifier uses AI to match the characteristics you describe or photograph against known error types and gives you a starting identification and value range. It's a strong first step, but for high-value or unusual finds, always get a second opinion from a professional grading service like PCGS or NGC before buying or selling based on the result.

Which tool should I use to find out what a normal (non-error) coin is worth?
Start with the Coin Value Estimator or Coin Value Checker for a quick read based on date, mint mark, and condition. For a deeper dive with full historical value charts by grade, the Price Guides & Value Charts hub covers most major U.S. series in detail.

Do I need to create an account to use the Coin Collection Portfolio Tracker?
No — the tracker runs entirely in your browser and doesn't require an account. Keep in mind that browser-based tools like this typically don't save your data permanently between visits unless the specific tool says otherwise, so it's best used for a quick snapshot rather than long-term recordkeeping.

How often is the Spot Price Tracker updated?
The Spot Price Tracker pulls live gold, silver, platinum, and palladium prices so you're seeing current market pricing rather than a static, outdated figure — useful before buying bullion or calculating melt value on silver or gold coins.

I'm new to coin collecting — where should I start?
Start with the Coin Value Estimator to get a feel for what you have, then try the Coin Grading Simulator to learn how condition affects value. From there, the Price Guides & Value Charts hub lets you look up your coin's full series to see if you're holding a common date or something more significant.
