||1861 $20 Clark, Gruber $20 Copper Dies Trial MS64 Red and Brown NGC. K-12c, R.6. Ex: "Col." E.H.R. Green. Clark, Gruber & Co. struck twenty dollar patterns in a variety of metals in 1861, including two copper issues, one with a plain edge and a different obverse from the regular-issue twenty dollar coins (K-12b), and a reeded edge pattern struck from regular-issue dies (K-12c). Both issues are rare in today's market, as are all Clark, Gruber & Co. patterns. A set of Clark, Gruber & Co. plain edge copper patterns (two and a half, five, ten, and twenty dollar denominations) was sold in lot 501 of Charles Steigerwalt's 12th Sale, with T. Harrison Garrett as the buyer. A similar set of reeded edge copper patterns was displayed at the 1914 ANS Exhibition by Denver collector Edward B. Morgan. We believe F.C.C. Boyd purchased that set in 1937. "Colonel" E.H.R. Green acquired another denominational set (including the present coin), which eventually passed to Eric P. Newman. The Green-Newman set includes a plain edge quarter eagle (K-9), and reeded edge examples of the other denominations (K-10c, K-11b, and K-12c). All four coins from that set are offered individually in this sale and it is unlikely that such a set will be offered again in the near future, as we believe the others have been broken up. The present coin is an attractive Choice example of the K-12c variety, showing a reeded edge, and struck from regular-issue dies that closely resemble the contemporary federal issue. The mostly brown surfaces show hints of original red, with subdued mint luster under the toning and only minor signs of contact. Census: 1 in 64 Red and Brown, 0 finer (8/14). Ex: "Colonel" E.H.R. Green; Green Estate; Partnership of Eric P. Newman / B.G. Johnson d.b.a. St. Louis Stamp & Coin Co.; Eric P. Newman @ $20.00; Eric P. Newman Numismatic Education Society.
