This set is housed in a single large size NGC holder, including: <strong>1990 No S Lincoln cent, FS-101</strong>; 1990-S Jefferson nickel; 1990-S Roosevelt dime; 1990-S Washington quarter; and 1990-S Kennedy half dollar.The highlight here is obviously the No S cent, one of the most intriguing and valuable of all modern U.S. Mint errors. This error resulted from the making in Philadelphia Mint of a Proof die that should have had an S mintmark. After being shipped to San Francisco it was used to strike an unknown number of cents for inclusion in 1990-S Proof sets. When Mint employees finally noticed the error, they were able to retrieve 145 examples from sets that had already been packaged for delivery, but which had not yet been shipped out. An unknown number of sets that included the No S cent had already been shipped, however, the first of which was reported by a collector in New York on July 18, 1990. Estimates on the extant population of this error have varied over the years and are difficult to pin down. Many examples may have gone to collectors who are not actively involved in the numismatic hobby and, as such, some owners might never known that their 1990-S Proof set contains a major rarity. Our offerings for specimens have been few and far between over the years, either individually or as part of complete sets, and they have always seen spirited bidding among advanced Lincoln cent and Proof set collectors. The present offering, as issued apart from being encapsulated by NGC, is sure to follow suit. (Total: 5 coins),,,,
