1918/7-S 25C MS64 认证号48101671, PCGS号5726

Per cataloger, "The 1918/7-S Standing Liberty quarter is a key issue and a major Guide Book variety, and for specialists of Standing Liberty quarters it is one of the most important acquisitions in the series. A single obverse die produced the variety and was apparently in use for an extended period of time, likely reflecting coinage demands in San Francisco in 1918. Examples of the variety flowed from the press to a hopper to circulation, where they subsequently went unnoticed by numismatic circles for nearly two decades. The first published account of the variety occurred in December 1937, when a Mint State example was described in Barney Bluestone's 36th auction catalog. Bluestone called the coin "excessively rare" and suggested that there may have been only "one or two other specimens known." That sentiment spoke to the alien nature of the overdate in the numismatic community at the time. As is the case with most 20th century overdates, the 1918/7-S quarter overdate feature was caused by the use of two different-dated working obverse hubs during the manufacture of the obverse working die. Presumably, the die was made in late 1917 or early 1918, during the transition between the 1917 and 1918 dates within the Engraving Department at Philadelphia. The first hubbing on the 1918/7-S obverse was with a 1917-dated hub; the hub was then coincidentally replaced with a 1918-dated one prior to the second hubbing. The same method of die preparation was responsible for the 1918/7-D nickel, the 1909/8 double eagle, the 1942/1 and 1942/1-D dimes, and the 1943/2 nickel. Most of these mint errors happened during wartime, perhaps because key Mint employees were sent off to war, or perhaps because the emergencies of war streamlined Mint procedures. In any case, there is no doubt how the overdate die was manufactured, even while some specialists debate the more nuanced discussion of whether or not the overdating was intentional or accidental. Regardless, the 1918/7-S quarter is today well established in the numismatic story, and it is especially sought after in Mint State, where it is a major rarity. The overdate is often compared to the 1916 Standing Liberty quarter -- the other top key date -- but in reality the two issues have no comparison in terms of Mint State rarity. Hundreds of Uncirculated 1916 pieces are known, compared to a few dozen Mint State 1918/7-S quarters." Obtained from Heritage Auction on 2/20/20 as a PCGS #38573787 MS63. Upgraded to a PCGS MS64 Pop 37/9 (12/23).

The 1918/7-S Standing Liberty quarter is one of the key date silver coin rarities of the 20th century. This variety was first noticed in the late 1930's and the first auction appearance was in December, 1937. Collectors began saving the few they could find in circulation. Today, the 1918/7-S is rare and relatively expensive even in the lowest grades. Mint state specimens are very rare and specimens with fully struck heads are extremely rare. Probably less than 100 mint state survivors exist and there are probably less than 10 gem MS65 or better specimens. There are only a handful of full head specimens and, as far as I know, there are no Gem MS65 full head specimens.
