***Auction Highlight*** 1877-cc Gold Liberty Double Eagle $20 Graded AU Details By USCG. Up for Auction is an almost Uncirculated example of the Carson City 1877 Double Eagle. In 1877, Chief Engraver William Barber made some modifications to the design of the double eagle that included spelling out the denomination in its entirety, among other minor modifications. The first set of these Type III dies had a technical problem that rendered them unsuitable for coining and it would not be until later in the year before 1877-CC double eagles would be produced. Even then, they were struck at a rate far slower than in the previous three years. Barely 2% to 3% of the 42,565 coins that were struck are thought to survive today, almost all of which are in the lower circulated grade levels
