The United States Mint 2021 Happy Birthday Coin Set features these proof coins from the San Francisco Mint:
The festive packaging—adorned with gift boxes and balloons—includes “Happy Birthday!” and “2021 United States Mint Happy Birthday Coin Set.” The coins are encapsulated in the folder so both the obverse (heads) and reverse (tails) sides of each coin can be seen. There is even space to write your personal birthday greeting to the recipient for a truly thoughtful and memorable gift.
A Certificate of Authenticity is printed on the back of the folder, and coin specifications appear on the back of the sleeve.
