Editor’s Note: This Five-Piece Set of No ‘S’ Proof Coins is featured in the upcoming 2010 April-May Milwaukee, WI CSNS US Coin Auction #1139.






1968 No ‘S’ Dime PR69 NGC. The first year of proof set production at San Francisco inaugurated this series of missing-mintmark rarities, and not surprisingly, the smallest-diameter denomination, the dime, was the subject. This mildly contrasted specimen has minimal patina over strong mirrors.






1970 No ‘S’ Dime PR68 Cameo NGC. Just two years later, another No ‘S’ dime appeared in a relative handful of proof sets, attracting considerable attention. This moderately contrasted example of the 1970 No ‘S’ variety has attractive frost-and-mirrors and little toning.






1971 No ‘S’ Nickel PR68 Cameo NGC. While a ‘No S’ proof quarter variety remains undiscovered, if it exists at all, the 1971 proof nickel with missing mintmark has become a collector favorite for its relatively large size. This captivating specimen is carefully preserved with an attractive cameo effect and exacting detail.






1983 No ‘S’ Dime PR69 Ultra Cameo NGC. A virtually flawless representative of the most recent No ‘S’ proof dime variety, practically black-and-white with gorgeous frost and smooth mirrors. Boldly detailed and impressive.






1990 No ‘S’ Cent PR68 Red Ultra Cameo NGC. The first and likely only No ‘S’ cent variety, since changes to Mint procedures have made future missing mintmark varieties far less likely. This specimen has bright copper-gold surfaces with thickly frosted devices and gleaming mirrored fields. A small planchet flaw is noted in the field below the Lincoln Memorial.
