Editorial policy

Care and official-coin claims should use the U.S. Mint and other primary sources. Consumer and estate guidance should use established numismatic organizations. Marketplace examples must be labeled as research, not proof of value.

Value language

Pages avoid stale guaranteed prices. They explain value drivers, direct users to completed sales and distinguish gross retail figures from actual proceeds.

Corrections

Material corrections should be made promptly when official documentation or credible numismatic evidence supports them.
