1877 Twenty Cent
With only 510 coins struck, all of which were Proofs, the 1877 has the lowest mintage and is the scarcest date in the twenty-cent series of 1875 to 1878. A large portion of the mintage is thought to have been melted after going unsold to collectors, resulting in an even more scant net-mintage of about 350 pieces.
The example to the left was sold by Stack's Bowers Galleries in the June 2022 Showcase Auction, where it realized $31,200.
