Prior to introduction of the nickel, five-cent pieces were very small silver coins called half dimes. Due to shortages of silver during and after the American Civil War, an alternative metal was needed for five-cent coinage, and the copper-nickel alloy still in use today was selected. Numerous problems plagued the coinage of nickels through the middle of the 20th century due to the extreme hardness of the alloy, but modern minting equipment has proven more than adequate for the task. |
