These coins, composed of silver, copper, and manganese, were produced during World War II due to nickel being a strategic war material. The presence of silver distinguishes them from regular coinage of the period. Examples can be found in numismatic circles and online marketplaces.
Their value stems from both their silver content and their historical significance. They serve as tangible reminders of wartime resourcefulness and represent a distinct period in American coinage history. Collectors and investors are drawn to them for these reasons.
