This type was intended to be a commemorative issue marking the 200th anniversary of Washington's birth. John Flannagan, a New York sculptor, was the designer. The initials JF are found at the base of the neck. Mint mark is on the reverse below the wreath. Minted from 1932 to 1964. The most valuable being a 1932d. Found my first one this year and it was my first silver quarter.
