The only known Branch Mint Proof 1876-CC Seated Liberty dime is crossing the auction block July 17 after being off the market the past four years.
The coin is the crown jewel of the Bob Simpson Collection of Proof dimes to be offered in Legend Rare Coin Auctions’ Regency VIII Sale in Las Vegas, Nev.
The auction is being held in conjunction with the PCGS Members Only show.
The coin last traded hands June 12, 2010, when Legend Numismatics sold the coin for in excess of $250,000 for placement in the Simpson collection, according to Legend’s Laura Sperber.
The Proof dime set comprises 47 coins dated from 1859 through 1891.
Numismatic researchers cannot reach consensus as to why the Proof 1876-CC Seated Liberty dime was struck. The LRCA lot description suggests between two and five examples were struck.
The Proof 1876-CC Seated Liberty dime first came to light when it was offered as the discovery piece in Stack’s Sept. 14 to 15, 1983, auction, where it was described as “Choice Brilliant Proof.”
The dime reappeared in Superior Galleries’ Jan. 5, 2008, sale where it realized $178,250. The coin was offered graded as PCGS Proof 65.
Sperber said despite selling his Proof dime collection, Simpson is just as aggressive as ever in his collecting. She said he has moved his focus into other areas.
Simpson’s most recent news-making purchase is the PCGS Proof 67, CAC, 1922 Peace, High Relief dollar that realized $458,250 in the June 2 portion of Ira & Larry Goldberg Auctioneers Pre-Long Beach Sale.
The Regency VIII auction will be held in Delfino #4003 at The Venetian/The Palazzo, 3355 Las Vegas Blvd. S., in Las Vegas.
