1862 Proof Liberty Head Gold $2.5 Quarter Eagle (Coronet Head)

The 1862 proof quarter eagle records one of the smallest documented proof emissions in the Coronet series, with John Dannreuther's research and Mint correspondence pointing to roughly 35 pieces struck. The drop from the 1861 figure of approximately 90 reflects the practical disruption of the Civil War on the Philadelphia collector market, with the suspension of specie payments at the end of 1861 effectively removing gold from circulation and dampening private demand for proof gold sets. Survivors fall in the 25 to 30 range across all grades on the combined PCGS and NGC census, making nearly every struck piece accounted for somewhere in the modern certified population. The companion business strike from Philadelphia recorded 98,543 pieces, a respectable but reduced output that itself reflected the wartime contraction of gold coinage. The proof issue therefore ranks among the genuinely scarce dates in the Coronet quarter eagle proof run.

Authentication on so small a population leans heavily on the combination of proof finish verification and documented provenance. Genuine examples display fully mirrored fields holding reflectivity right up to the rim, squared rim profiles characteristic of heavy proof striking pressure, and crisp wire-rim transitions where the field meets the rim border. Liberty's hair curls and the individual eagle feathers should show the granular sharpness that fresh proof dies impart, distinct from the softer flow on the corresponding business strike. Weight should sit close to the 4.18 gram standard on the 90 percent gold alloy, with the 18 millimeter diameter and reeded edge within tight tolerance. Because survival is low and modern certified appearances are infrequent, every claimed example carries a documented chain of ownership, and pedigree to a named American cabinet provides authentication weight that surface analysis alone cannot supply.

Auction appearances are measured in multi-year intervals, and the 1862 proof typically commands a premium over the 1860 and 1861 dates when offered in equivalent grade. Surviving examples cluster in the Proof 60 through Proof 64 range, with Cameo designations rare given period die preparation. Civil War provenance carries collector appeal beyond pure numismatic value. See the full Liberty Head Quarter Eagle series history.
