The Roosevelt Dime, designed by John R. Sinnock, began mintage in 1946 and continues to be minted today. This set of ten Roosevelt Dimes  was struck in 1957 at the Philadelphia Mint and graded in Proof 69 condition. Composed of 90% pure silver, these stunning coins honor America's 32nd President Franklin Delano Roosevelt. Out of all 1957-P Roosevelt Dimes struck, significantly less than 1% have been graded in PF69 condition. With such a low Proof 69 population, these 1957-P Roosevelt Dimes  are tremendous Condition Rarities.
