The 1877 has one of, if not the lowest mintage among Proof trade dollars. Either 510 or 710 Proofs were struck, the discrepancy stemming from the uncertain status of 200 coins delivered in February. Were they Proofs or circulation strikes? We may never know. What is known with certainty, however, is that the 1877 is one of the more underrated Proofs of this type, even the often-quoted mintage of 510 pieces insufficient to catch the attention of most collectors who focus on the Proof-only trade dollars of 1878 to 1883. In the finest grades, the Proof 1877 is a condition rarity. Like most of these issues, Cameo contrast has been designated on roughly one quarter to one third of the certified population.

The example to the left was sold by Stack's Bowers Galleries in the August 2010 Boston Auction, where it realized $13,800.
