1858

The 1858 eagle is the legendary Philadelphia rarity of the No Motto Liberty Head series. With a reported business-strike mintage of just 2,521 pieces, it stands as one of the smallest production figures ever recorded at the parent mint for the $10 denomination across the entire 1838-1907 run. The total places it firmly inside the small handful of dates that define the upper tier of Liberty Head Eagle key dates, and Doug Winter has long flagged it as a major expense point in any year-set attempt across the No Motto era. Surviving population is correspondingly thin: PCGS estimates roughly 25 to 30 pieces known across all grades, with the upper register dominated by a single MS64+ specimen that brought $276,000 in Heritage's May 2007 Platinum Night sale and remains the auction record for any 1858 eagle, including proofs.

Surviving examples concentrate in Very Fine through Extremely Fine, with About Uncirculated pieces decidedly scarce and Mint State coins in the low single digits. Strike quality follows the Philadelphia norm for the type, acceptable detail with typical softness on Liberty's hair curls and the eagle's shield. Authentication is mandatory at any grade. The classic counterfeit playbook for low-mintage Philadelphia eagles is altered-date work using common neighbor years, and added-mintmark fantasies grafted onto a genuine 1858-P host are documented across the No Motto market. Standard physical checks apply: 16.718-gram weight target, specific gravity near 17.2, and a reeded edge consistent with original strike. Given the population, every offered example should ship with current PCGS or NGC certification, raw 1858 eagles claimed at AU or higher warrant deep skepticism until verified.

Collecting reality on the 1858 is straightforward: most working collectors will never own one, and those who do typically land in Very Fine to Extremely Fine after a multi-year search. Winter's standing recommendation for set builders is a problem-free EF if budget and supply align. Mint State pursuit belongs to a small specialist tier where competition for any new market appearance is intense and pricing tracks the broader trophy-coin environment rather than published guides.
