Description
The 1861 Proof Clark, Gruber & Co. Twenty Dollar is a proof dollar struck at the Philadelphia Mint, part of the Colorado Gold (1860-1861) series. Produced during the Civil War, when coin hoarding caused severe shortages and the Mint experimented with new compositions to keep coins in circulation. As a proof issue, this coin was struck multiple times on specially prepared polished planchets using polished dies, producing mirror-like fields and frosted design elements prized by collectors. Struck at the original U.S. Mint facility, in continuous operation since 1792. Auction record: $23,000 MS63 09-22-2010 Heritage Auctions. Struck in gold (approximately .900 fine), weighing 33.44 grams, 34 mm in diameter, with a reeded edge. Cataloged as PCGS #10153.
