Two die varieties are known. On the first, the mintmark is located over the NT in TWENTY. On the second, the mintmark is placed over the upright stroke of the N in TWENTY.
The sales records of 1870-CC Double Eagles are as distinctive as their strike and appearance. Generally, this date becomes available in spurts. Two or three pieces will come onto the market, eventually be absorbed, and then disappear for many years. After, it becomes nearly impossible to find a piece for sale. Nearly every example of this date is owned by a serious collector and these coins trade far less frequently than pieces owned by investors or dealers.
The 1870-CC Double Eagle is usually seen in bag marked Very Fine grades. It is infrequently available in Extremely Fine and most of the few known XF’s are no better than low end XF40 coins. Choice Extremely Fine pieces are exceedingly rare. The highest grade seen by a major grading service is AU58, which was stolen during transit from PCGS in 2011. There is no known 1870-CC Double Eagle which grades Mint State.
