1873 Closed 3 Proof

The 1873 Proof Liberty Head Double Eagle is a 25-piece Philadelphia issue cataloged as JD-1 by John Dannreuther, and every surviving example carries the Closed 3 logotype. Earlier handlings occasionally suggested no proof was struck this year, but the record is firm across modern scholarship, with PCGS recognizing the issue under cert 9088 and the Type 2 With Motto proof run documented across all eleven years from 1866 through 1876. The Closed 3 detail is the central collecting note. The proof striking was completed before Chief Coiner A. Loudon Snowden ordered new circulation dies with a more open knob on the 3 because the original was being misread as an 8 in commerce. That reform applied only to circulation dies; proofs were already struck and delivered.

Survival across all grades is estimated at roughly seven to twelve coins, placing the date at High R.7 in the Sheldon framework. Several of the known pieces have been cleaned or lightly mishandled over the past century, which compresses the unimpaired population into a very narrow band centered in the PR63 to PR64 range. PCGS and NGC populations confirm that compression, with Cameo designations infrequent and Deep Cameo or Ultra Cameo examples genuinely rare. Authenticators rely on the Closed 3 die diagnostic, the depth of the proof strike on Liberty's hair detail, and the mirrored field quality consistent with documented JD-1 working dies. The Open 3 logotype is never seen on a genuine 1873 proof, so any candidate showing the open knob on the 3 should be rejected immediately.

Market appearances are infrequent and separated by long gaps. The current benchmark is the PR65 Ultra Cameo NGC example that realized $230,000 in Heritage Auctions' Central States Platinum Night sale held April 27 to 30, 2011, a result that remains the public record for the date and reflects the appeal of cameo contrast on a genuinely rare proof issue. Lower-grade pieces in the PR63 to PR64 band trade through private channels more often than public sale, with pricing supported by the limited supply and the late-Type 2 cluster of small proof mintages that culminated in the higher 45-piece figure for 1876. Collectors pursuing this date generally work within the broader Liberty Head Double Eagle series history.
