1867 Proof Liberty Head Gold $2.5 Quarter Eagle (Coronet Head)

The 1867 Liberty Head Quarter Eagle Proof was the second postwar proof delivery for the denomination, with Mint records indicating approximately 50 pieces struck for collector and institutional sale. The figure was a modest expansion over the 1865 and 1866 deliveries, reflecting cautious recovery in numismatic subscriber activity as Reconstruction-era commerce stabilized. Modern survival estimates place the population at 30 to 40 specimens across all grades, a figure consistent with the steady attrition that affected all small Civil War and postwar proof gold deliveries through fire, melting, and the routine handling losses of cabinet ownership across the past 159 years. The issue is paired with a regular-strike mintage of just 3,250 business pieces, making both formats genuinely scarce in the current market.

Authentication centers on the deeply mirrored fields and characteristic luster of well-preserved postwar proof gold, with square inner rim definition produced by the basined dies and the crisp wire rim distinctive to repeated-impression proof manufacture. Standard specifications must hold throughout: 4.18 grams within tolerance, 18-millimeter diameter, .900 fine alloy with reeded edge and coin alignment. The strike sharpness on Liberty's hair detail and the eagle's feather definition reaches a level the business-strike production of the period cannot match, and diagnostic die polish lines are visible through the fields under low magnification. Cameo contrast varies across the surviving group, with full Cameo or Deep Cameo designation commanding substantial premiums. Pedigree research provides essential authentication corroboration because so few examples have ever appeared in documented public offerings.

Market activity for the 1867 quarter eagle proof has been measured but consistent, with Heritage and Stack's Bowers offering certified examples at intervals of one to three years. PR-63 and PR-64 specimens have realized strong five-figure results in recent sessions, while Cameo and gem-grade pieces have approached or crossed the six-figure threshold when offered to a competitive room. The Eliasberg, Bass, and Trompeter pedigrees all contributed coins that established price benchmarks still referenced in current cataloging, and ownership traceability through these holdings adds meaningful premium when present on a holder. Date collectors pursuing the complete Liberty proof quarter eagle run treat this issue as a manageable but still demanding 1860s acquisition. See the full Liberty Head Quarter Eagle series history.
