This lot consists of a grouped collection of United States proof coin sets, each housed in its original government-issued presentation case. The sets appear to span multiple years, with individual cases labeled by year and featuring the Great Seal of the United States on the exterior. Each set includes multiple proof-struck coins with mirrored fields and frosted devices, presented in clear holders designed to protect and display the coins. Proof sets like these are popular with collectors for their superior strike quality, historical continuity, and original packaging, making this an attractive opportunity to acquire multiple years at once. Ideal for collectors looking to expand a proof set run or investors seeking established U.S. Mint products.

Condition Report
All proof sets appear to be in very good condition, housed in original presentation cases with expected light surface wear to the outer cases from storage. Coin holders appear intact with no obvious damage noted. Individual coins show typical proof quality with reflective surfaces; condition has not been professionally graded.
