United States Proof Sets are minted in San Francisco. They are produced from carefully selected planchets, or coin blanks, that have been burnished to a high luster. The polished blanks, which are carefully handled to minimize scratches and abrasions, are struck on specially adapted coining presses. Each coin is struck at least twice to bring forth the most minute detail with remarkable clarity. 2008 Clad Quarter Proof Sets are NOW AVAILABLE.
