Corrections and data errors

If you spot an error in a coin specification, formula, or calculated value, please tell us:

• Which coin or calculator has the error
• What the error is
• The correct value and its source (US Mint URL, Coinage Act reference, etc.)

We investigate all corrections and update the site when errors are confirmed.
