"About Uncirculated, cleaned" (illustrated above).  Ex - Early American History Auctions, Inc.'s Mail Bid Sale, June 9, 2001, Lot 1475, where it was described as follows: "1852 Wass, Molitor & Company $5 Gold, About Uncirculated, cleaned.  Small Head, Rounded Bust, and (according to Breen) "Very Rare." This example ranks among the finest known, as it has a full, even strike and the details rival those on Breen's plate for his number 7922. Both sides have been cleaned and the reverse has had some tooling done in the area of the lowest arrowhead to remove some roughness there. Nevertheless, this is an important coin not only for its rarity but for its above-average condition."
