1942 Doubled Die Obverse DDO-001
Error
Description
One of the most celebrated varieties in the Mercury Dime series, DDO-001 on the 1942 Philadelphia issue displays strong spread on the date manifesting as a dramatic 42/41 overdate — the digits 42 visibly superimposed over an underlying 41, creating one of the clearest overdate effects in twentieth-century U.S. coinage. Medium spread also appears on IN GOD WE TRUST, reinforcing the hub displacement across the lower obverse. Cross-referenced as 1-O-III in the CONECA system — variety 1, obverse, Class III design hub doubling — this classification identifies displacement during the die creation process. The prestigious Fivaz-Stanton FS-101 designation confirms its status as a major variety recognized by all grading services, ensuring consistent attribution and sustained market demand. Die markers UVC-153 and DMR-003 confirm the working die. The 1942 Mercury Dime was struck at the Philadelphia Mint in 90% silver at 2.5 grams. Examine the date under 5x magnification, where the underlying 41 digits are clearly visible beneath the 42, particularly in the final two numerals.
