Feedback

This form reaches the people who build Coin Guide. It is the same form that has always been on this page, so if you have written to us before, nothing about it has changed.

What is worth telling us

Anything specific is more useful than anything general. The most valuable messages we get are these:

• A price on a page that does not match what you see elsewhere — tell us the page and where your figure comes from.
• A coin, a year or a mint mark that is missing from the site.
• A page that is wrong about a variety: a doubled die, a missing mint mark, a date we describe as common that is not.
• Something on the site that does not work — a broken link, a table you cannot read on a phone, an image that never loads.
• A problem with the Coin Guide app, including anything about a purchase or a subscription.

How we handle prices

Every price on this site is copied from a named source and dated — a PCGS Price Guide value, a PCGS population figure, or a recorded auction result. We do not estimate values ourselves, and we cannot appraise a coin from a photograph or a description. If a figure on a page looks wrong to you, say which page and which number, and we will check it against the source it came from.

The site and the app are not the same thing

Coin Guide is both a mobile app that recognises coins from a photo and this reference site about what U.S. coins are worth. Feedback for either one arrives through this form; saying which of the two you mean saves a round of questions.
