The 1942/41 Mercury Dime is generally termed an overdate; it is actually a doubled-die error—the obverse die from which the coins were struck took one impression from a 1942-dated hub and one from a 1941-dated hub (until the 1990s, dies required two strikes from a hub for the design to be fully impressed). A truly rare variety in numismatics and in about uncirculated condition with full bands displayed on the reverse. Many Mercury dimes were not fully struck, meaning that design detail was lost even before the coins entered circulation. Exceptionally well-struck dimes display "full bands", that is, the horizontal bands on the fasces show full detail. In circulation, the reverse tended to more readily display wear due to a lower rim in relation to the relief of the design. Most well-circulated dimes show more wear to the reverse.
