Collection of five official U.S. Mint proof sets spanning 1961-1964, including an additional 1964 P proof set. Each set contains original government packaging with Treasury Department envelope and hermetically sealed plastic coin holders featuring the Philadelphia Mint emblem.

This collection includes all denominations of the era: Lincoln cent, Jefferson nickel, Roosevelt dime, Washington quarter, and Franklin/Kennedy half dollar. All coins exhibit the brilliant mirror-like surfaces and sharp strikes characteristic of proof coinage from this period. The 1964 sets are particularly significant as the final year of 90% silver coinage and first year of the Kennedy half dollar.

Condition Notes: All sets remain in original government packaging with minimal toning. Plastic holders show expected age-related clarity issues but remain intact. Treasury envelopes show typical aging, slight discoloration, and handwritten year markings on some. Coins maintain excellent proof surfaces with minimal spotting. Refer to the pictures and in person inspection for condition.
