Can I replace a Certificate of Authenticity?
Answer ID: 125

Not all United States Mint products come with a Certificate of Authenticity (COA). For example, proof sets contain COAs, but medals typically do not. In some instances, COA language is included in the product packaging.

To ensure that you have a genuine United States Mint Certificate of Authenticity (rather than a replica), look for these two things on your COA:

  1. A signature of a senior official of the United States Mint.
  2. An image of the official U.S. Treasury seal and/or the United States Mint seal.

If you have lost your COA, Contact Customer Service to see if a replacement is still available.
