About this coinHistory

Proof output peaked at approximately 1,000 coins in 1870, the highest proof mintage in the series. The increase reflected continuing collector demand as the denomination approached its end. The 1870 proof is consequently one of the more available proof trimes, and it represents a good starting point for collectors building a proof set without the extreme rarity premiums of the earlier years.
