In uncirculated grades, the 1942/1-D is a true rarity, with only a handful of survivors. While not necessarily a rare coin, the 1942/1-D Mercury dime is scarce enough and enjoys a high enough demand that better-graded examples bring huge premiums. Part of the allure behind this overdate is the fact that the 1942/1 overpunch is clearly visible to the naked eye. Like its Philadelphia-minted counterpart, the 1942/1-D Mercury dime is a widely recognized and collected variety that has drawn attention from numismatists since its earliest days. Struck in Denver and designated as a Business (MS) strike, this coin is made of 90% silver 10% copper from a mintage of 60,740,000 struck. The 1942/1-D Ten cents is part of a series of Winged liberty head (Mercury) dime coins struck from 1916-1945.
