1889

The 1889 Liberty Head eagle is one of the quiet rarities of the late With Motto run, a Philadelphia issue whose roughly 4,440-coin mintage drops it into the bottom tier of regular-issue $10 gold for the entire 1838-1907 series. Output collapsed because depositors were directing bullion into double eagles and the Morgan dollar, leaving the eagle denomination almost ornamental at the main mint. The result is a date that sits awkwardly in the album: harder to find than the headline branch-mint scarcities yet often overshadowed by them, and substantially rarer than the 1889-S that shipped 425,400 pieces from San Francisco the same year.

Authentication carries unusual weight on a date this thin. A genuine eagle weighs 16.718 grams in 90% gold with a specific gravity near 17.2, and any candidate that runs noticeably light, displays a soft seam at the rim, or shows the granular fields characteristic of struck-counterfeit transfer dies should be set aside. Because no mintmark sits on the reverse, alteration risk runs the opposite direction from branch issues, the danger is a removed S or O misrepresented as a Philadelphia coin, so reverse field tooling and rim disturbance behind the eagle's tail merit close examination. PCGS estimates only fifty to one hundred survivors across all grades, with Mint State pieces particularly elusive; certified populations thin sharply above MS61 and Gem material is essentially absent. Doug Winter flags the 1889-P as the rarer of the two business strikes this year.

For the collecting market this date is a Top tier purchase that rewards patience over urgency. A PCGS MS62 brought $8,519 at a Legend Rare Coin Auctions sale in January 2019, and choice uncirculated examples now trade in the low five figures when they appear at all. The natural strategy is to take a strong AU example with original orange-gold patina rather than chase a marginal Mint State coin at a speculative premium, the population gap above MS62 means upgrade opportunities are years apart.
