Jaime Hernandez: The 1942-D is not considered a low mintage issue. However, it is considered a key date in the Jefferson Nickel circulation strike series. Possibly do to the war and the lack of coins in circulation during that era, this date and mint mark circulated widely. Thus, coins in uncirculated condition are considered scarce and command a strong premium. As of this writing Uncirculated examples command about $50 each in MS60-MS63 condition. This is one of the most expensive dates in the circulation strike Jefferson Nickel series in Uncirculated grades.
