1873 Proof

The 1873 Trade Dollar Proof is the first-year proof of the series, struck at the Philadelphia Mint under formal Mint Director proof procedures with a documented mintage of 865 pieces per the Mint Director annual report. The Coinage Act of February 12, 1873 authorized the new 420-grain silver Trade Dollar, and Philadelphia struck the initial proof set later in 1873 alongside other 1873 proof denominations as part of the standard collector subscription. The 1873 Proof carries the Type I obverse and Type I reverse hubs that define the early series, with William Barber's Seated Liberty design facing west and the perched eagle on the reverse.

Authentication of an 1873 Trade Dollar Proof requires careful examination of the strike quality, mirrored field character, and surface preservation under five to ten power magnification. The 1873 Proof shows fully struck Liberty drapery and eagle feather definition with deep mirror fields that distinguish formal proof production from business-strike prooflike examples. PCGS, the Professional Coin Grading Service, and NGC apply standard proof grading conventions across the 1873-1883 Trade Dollar proof sequence. Cameo and Deep Cameo designations are uncommon for 1873 Proof examples, reflecting the brilliant rather than frosted device finish typical of early Trade Dollar proof production. The 1873 Proof certified population at the standard grading services confirms production-range survival across the Proof-60 through Proof-65 tier.

The 1873 Trade Dollar Proof is a regular-classification proof entry on this site under the standard catalog convention for Trade Dollar proofs, with the rarity narrative carried in the prose rather than the badge tier. The 1873 Proof pairs with the broader 1874 through 1883 proof sequence as the matched original-series proof production set, distinct from the proof-only 1884 and 1885 entries that close the series. Auction records for confirmed 1873 Proof examples cluster in four-figure prices for Proof-63 and Proof-64 grades, with Cameo premiums applying at higher grade levels.
