The 1942/1 Mercury Dime stands as one of the most intriguing and valuable error coins in American numismatics.
This overdate error, where a 1942 die was mistakenly punched over a 1941 die, has captivated collectors for decades.
Recent auction records and discoveries have reignited interest in this rare coin, making it a hot topic in the coin collecting community.
Understanding the Overdate Error
The overdate occurred when the U.S. Mint, during the die preparation process, inadvertently used a 1941-dated hub to create a die intended for 1942 coinage.
This resulted in the underlying “1” from 1941 being visible beneath the “2” in 1942 on the coin’s date. Such errors are rare, especially in the 20th century, due to improved minting processes.
Mint Locations and Rarity
- Philadelphia Mint (1942/1): Estimated 3,600 surviving examples.
- Denver Mint (1942/1-D): Slightly rarer with approximately 3,200 known specimens.
Both versions are scarce, especially in uncirculated grades, and are highly sought after by collectors.
