1872

The 1872 Philadelphia eagle stands as one of the toughest business-strike issues of the entire With Motto series, struck in a Reconstruction-era environment where domestic gold coin demand had collapsed and circulating eagles were essentially absent from commerce. Reference data records a circulation production of just 1,620 pieces, among the lowest figures for any Philadelphia $10 Liberty, comparable to the celebrated 1858 and trailing only the 1875 and 1873 in absolute scarcity at the parent mint. Most of the original delivery was almost certainly melted or exported to satisfy international gold settlement, leaving a survival pool that PCGS estimates in only the low double digits across all grades.

For attribution, look first for the Type 2 With Motto reverse, with IN GOD WE TRUST on a banner above the eagle, and the absence of a mintmark below the perched bird, that single field is the only mint-of-origin indicator and contemporary forgeries have been documented where mintmarks were skillfully removed from common Carson City or San Francisco eagles to fabricate a Philadelphia rarity. Authentication should confirm a weight of 16.718 grams within tolerance and a specific gravity reading of approximately 17.2; any deviation in the date area's metal flow, or any disturbed field around the lower reverse where a removed mintmark might leave tooling, warrants rejection. Genuine survivors typically show even, honest circulation wear, frequently with the rose-gold toning characteristic of original-skin Philadelphia gold of the 1870s, one NGC AU-55 example with that exact toning realized $10,800 at Heritage in December 2023, a useful market anchor for the grade.

For collectors, the 1872 sits firmly in Doug Winter's top tier of With Motto Philadelphia eagles and is widely regarded as essentially unobtainable as anything beyond a circulated example; uncirculated pieces are the province of advanced specialists and emerge at auction only at multi-year intervals. Demand is sustained both by date-set collectors trying to complete a Philadelphia run and by registry competitors, with the strongest pricing reserved for problem-free coins carrying CAC approval.
