1879 Proof Seated Liberty Half Dollar

The Mint struck 1,100 proof half dollars in 1879, exceeding the circulation mintage of just 5,900 coins. From 1879 through 1890, proof production would consistently rival or exceed circulation-strike output, an unusual inversion that reflected the half dollar's reduced commercial role under the Bland-Allison Act.

The proof-to-circulation ratio was unlike anything in the series' history. For most of the Seated Liberty era, proofs had been a tiny fraction of total production. Beginning in 1879, both formats served the same small collector market, and the traditional distinction between commercial coinage and collector proofs essentially disappeared. The 1879 proof opens the twelve-year period when proof and circulation half dollars were produced in roughly equivalent quantities for an exclusively numismatic audience.
