Civil War Tokens (CWTs) are tokens that were privately minted and distributed in the United States between 1860 and 1870. They were used mainly in the Northeast and Midwest. The widespread use of the tokens was a result of the scarcity of government-issued coinage during the Civil War.
Civil War tokens are divided into three types: store cards, patriotic tokens, and sutler (is a civilian merchant who sells provisions to an army) tokens. All three types were utilized as currency, and are differentiated by their designs. The collectible value of the tokens is determined chiefly by their rarity. This UNION FOREVER with shield pattern is one of the more common varieties.
Fully uncirculated Civil War tokens are very rare and can fetch several $100s of dollars.
