Heritage noted “a distinctive slender mark above star 13 is a primary identifier.” The description relates the shallow cracks in the planchet with a shortage of parting acids on the West Coast in 1854, when the San Francisco Mint opened, stating, “Our theory is that the network of cracks seen on this piece may have something to do with impurities in the ore from which the coin was struck.” It may have been impossible at the time to completely separate the gold from impurities in the native alloy, and the Mint-made defects resulted from these impurities in the gold ore. The cataloger looked at images of the same coin from earlier auction appearances that show hairline scratches across the prominent flaws in the planchet, “but they are less evident now” (presumably responsible for the “Repaired” notation by PCGS). Heritage praises the sharp remaining detail, characterizing the coin as “actually one of the finest known” in terms of sharpness, adding, “a couple of planchet depressions are seen in the upper left obverse field.” No Mint State survivors remain, and the finest example grades only About Uncirculated 50.
