拍品描述： Missouri—St. Louis. Undated (ca. 1867-1869) Durfee & Peck. 50 Cents in Merchandise. Copper. 24 mm. Curto-49. MS-64 RB (PCGS). Boldly prooflike with deep orange and red toning highlighted by attractive blue iridescence. A few tiny specks on the reverse, but beautifully preserved. One of the nicest we have seen, and certainly the nicest in a decade as the last copper specimen in our archives dates back to September 2009. This one has been off the market since our famous Clifford sale in 1982. From our (B&R) sale of the Clifford Collection, March 1982, lot 377.
