Obverse Dies: 7 Known
Seven different obverse dies have been identified for 1842 Philadelphia coinage, including the proof die. Segragating 1842 obverse dies is difficult due to minor differences in date position placement.
The 1842 plate coin variety (Ahwash 3) is always seen with a bold rim cud from Star 3 to Star 5. The date digits are heavily punched with the 84 digits touching. A faint die crack joins Stars 7 and 8 with Liberty's head. The reverse die features an abundance of die lines between the right rim and wreath. A large series of parallel die lines originate from the right rim into the letters ERICA of AMERICA. Another significant die line passes through the first S of STATES.
Plate Coin: Fortin 103a, Ahwash 3, Rim Cud at 10:00, Even White and Lustrous Example, Finding an Acceptable Upgrade has been Quite Difficult
The 1842 Dime is a fairly common coin which behaves (if coins could behave) like the 1841 and 1843. These three dates have nearly identical total populations and there are similar quantities of Mint State examples of each date. The typical Mint State 1842 Dime is MS63 or MS64. Gems are very scarce and only a handful of MS66 examples sit atop the Condition Census. The strike quality of this date is good, though the stars, denticles, and lower right wreath are sometimes weak.
Researcher Gerry Fortin has identified eight different varieties of the 1842 Dimes, one of which was used to strike Proof coins.
