Editorial and corrections policy

People use these pages to decide whether a coin deserves a closer look or a trip to an expert. A wrong mintage or a wrong silver content can make them sell a scarce coin for its metal or spend money grading a common one, so every figure points back to the publication it was read in.

What we read

• the Bureau of the Mint’s 1981 book of coins manufactured from 1793 to 1980, and the Mint’s annual reports;
• usmint.gov: coin specifications, mint marks, history of circulating coins, penny FAQs, press releases and production reports, including archived copies where the Mint has removed a page;
• the United States Code and the Code of Federal Regulations on govinfo.gov;
• the World Bank’s monthly commodity prices and a live silver and copper price service.

Sources we refuse

Dealers, auction houses, price guides, forums and grading services never supply a figure here. A fact we cannot find in an official publication is not presented as a fact; where official sources are silent, the page says so. No collector price is published, because none can be sourced freely.

Review cycle

The metal prices are re-read every month by a scheduled script and live in the browser. Specifications and dates are re-read against the Mint’s pages when a change is announced, such as a new design or the end of a coin.

Corrections

1. We open the source again.
2. We correct the data file and add an automated test for the case.
3. The site rebuilds and every page shows the new date.

Independence

No mint, dealer or grading service pays for or reviews what is published here, and the site carries no affiliate link. See also the method page. Version of October 26, 2026.
