1999 Silver Proof Set. Since 1992, the U.S. Mint has issued special silver proof sets in addition to regular base-metal proof sets. These sets revived the tradition of 90% silver dimes, quarters and half dollars. The 9-coin 1999 silver proof set is especially prized because it contains the coveted first five Statehood quarter proofs (Delaware, Pennsylvania, New Jersey, Georgia and Connecticut) as well as the silver dime and half dollar and the cent, nickel and Sacagawea dollar. Its 804,565 mintage was well below the first 1992 silver proof set's output of a million.
2003 Silver Proof Set. Unlike regular U.S. proof sets, this 10-coin silver proof set features seven 90% silver issues, including the five statehood quarters, the Roosevelt dime and Kennedy half dollar. Since silver coins have not been minted for circulation since 1964, this set is the only way to obtain these issues with precious metal content. And silver proof set mintages are always far below the regular proof set's production. Finest-quality proof minting features double-struck engravings with elegant frosted finishes that sets them off against brilliant mirror backgrounds.
