An extremely rare 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 a highlight of the Bob Simpson Collection of Proof Dimes to be offered in Legend Rare Coin Auctions’ Regency VIII auction held in conjunction with the PCGS Members Only show at The Venetian/The Palazzo in Las Vegas, Nev.
The coin is graded Specimen Proof 66+ by Professional Coin Grading Service with a “(BM)” designation referencing the coin as a special Branch Mint strike. It is also stickered by Certified Acceptance Corp.
Numismatic researchers cannot reach consensus as to why any Proof 1876-CC dime was struck. The Legend lot description suggests two to five examples were struck in celebration of the 1876 United States Centennial.
Also being offered in the July 17 auction are Simpson’s matched original Proof sets from 1856 through 1859.
The offered Branch Mint Proof 1876-CC Seated Liberty dime last traded hands June 12, 2010, when Legend Numismatics sold the coin for more than $250,000 for placement in the Simpson Collection, according to Legend’s Laura Sperber.
The Proof dime collection comprises 47 coins dated from 1859 through 1891. Also among the 47 dimes in the collection is an 1880 Seated Liberty coin, graded PCGS Proof 67, CAC.
According to Legend, 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 sold for $9,900.
The coin there was offered as a “Choice Brilliant Proof.”
