This 2020 Silver U. Proof Set comes with a certificate of authenticity and was struck in San Francisco. The set includes uncirculated coins and is composed of silver. The denomination of the coins is not specified in the set. The strike type is proof and the composition is silver. The set is ungraded and has not been certified. The box is a bit rough, but the coins inside are just fine. This set is a great addition to any coin collection and is a must-have for anyone who loves collecting U.
