This is a 1964 P Silver US Mint Set cut from its Mint Set Cello and placed in a Whitman Plastic holder. These coins are untouched from their Mint Set packaging and appear as sent from the Mint. Remember 1964 was the First Year of the Kennedy Half Dollar and the first and last year of the 90% Silver Kennedy Half Dollar minted for normal Circulation. Also the last year of the 90% Silver Washington Quarter and Roosevelt Dime minted for Circulation. A Year of big changes in US Coinage.
