1918/7-S Standing Liberty Quarter. FS-101. MS-65 (PCGS). CAC. This is a truly amazing example of one of the leading rarities in the Standing Liberty quarter series. Splendid Gem quality surfaces are fully lustrous with a softly frosted texture. Both sides present as virtually brilliant, but there is some delicate toning in iridescent champagne-pink and powder blue that provides strong visual appeal. Both the surface preservation and the strike are superior for this challenging variety, the strike being nearly full with emerging detail to Libertys head and a bold, clear 7 underdigit. As one of the highest graded survivors of a prized overdate, this exquisite Gem will be an important addition to the finest Standing Liberty quarter set.The 1918/7-S was created when Mint personnel reworked a leftover 1917-dated quarter die for use the following year. This was done in the Philadelphia Mint, where all dies were prepared at that time. Once on the West Coast this overdate die struck an unknown, although presumably small number of the 11,072,000 quarters attributed to the San Francisco Mint in 1918. Although the overdate feature is quite bold and easily discerned with the naked eye, it escaped the attention of numismatists until 1937, by which time the vast majority of examples had entered circulation. Scarce even in worn condition, the 1918/7-S is very rare in Mint State. The remarkable Pogue coins is expertly preserved and stands head and shoulders above virtually all other Mint State survivors known in terms of surface quality. A leading highlight of the Standing Liberty quarters in the Pogue Collection, and an important bidding opportunity for the astute collector.
