1842

The 1842 Philadelphia quarter eagle carries a coinage of just 2,823 pieces, the lowest Philadelphia mintage of the Coronet quarter eagle's first decade and one of the smaller figures in the entire 68-year series. It sits as a sub-3,000 sleeper that has long been overshadowed in the price guides by the contemporaneous branch issues of Charlotte and Dahlonega, even though the survivor pool from the senior mint is comparably thin. Independent census work suggests fewer than 200 examples remain across all grades. The early 1840s were a slow stretch for quarter eagle demand at Philadelphia, with the half eagle and eagle absorbing the bulk of the Mint's gold-conversion work, and the small 1842 figure reflects that allocation rather than any production difficulty with the design itself. The Coronet hub work from Christian Gobrecht had stabilized after the 1840 introduction, and the dies for this year share the same general execution as the rest of the early Type 1 group.

Authentication for the 1842 Philadelphia begins with the standard specifications. A genuine planchet weighs 4.18 grams in 0.900 fine gold with specific gravity near 17.2, and any reading outside narrow tolerances flags either a cast counterfeit or a plated-base reproduction. The reeded edge should show consistent vertical file marks rather than the seam-line evidence common to cast fakes, and the coin alignment is the upright-down configuration standard for pre-1907 federal gold. Because the 1842 is a no-mintmark issue, removal of a C, D, or O mintmark from a comparably scarce branch coin to create a counterfeit Philadelphia piece is a documented alteration vector worth examining at the standard mintmark position above the denomination. Cast fakes from the 1970s and 1980s remain the dominant counterfeit category for this date, identified by edge-seam evidence, granular field texture, and softness at high points where a struck coin would show crisp transition.

Market behavior for the 1842 Philadelphia tracks its survivor profile. Circulated coins in problem-free Very Fine through Extremely Fine grades surface at major auctions with enough regularity that a patient buyer can complete an early Coronet date run, while About Uncirculated examples are scarce and Mint State pieces are rare.
