PCGS PR 70 DCAM 1992 S Kennedy Silver $0.50 96834.70/32039237 https://www.pcgs.com/cert/32039237 Weight: 11.3g Metal: 90% Silver; 10% Copper Designer: Gilroy Roberts/Frank Gasparro Mintage: 1,317,579 Edge: 150 Reeds Diameter: 30.61mm Mint: San Fransisco Beginning in 1992, the Mint offered special, 90% silver Kennedy Half Dollars for sale to collectors; these are available only as Proofs. In 1998 only, 90% silver Half Dollars were issued in both brilliant and matte Proof formats. The later 90% silver Half Dollars are included with the 1964 issues as a distinct type because of their similar metal content. This is the first year in which the Mint struck 90% Silver Proof Kennedy Half's with an S mint mark. The last time the Mint had struck 90% Silver Proof Kennedy Half's was in 1964. However, the 1964 Proofs did not contain the S mint mark. Additionally, the new Proof Silver Kennedy Half's struck from 1992 and after had slight differences in the details of the design. The 1992-S Silver Proofs had the lettering thicker on both the obverse and reverse than that of the 1964 Proofs. The Proof Silver Kennedy Half's have been struck by the U.S. Mint and sold in Silver Proof Sets every year since 1992.
