Tax tokens of Colorado USA

Sales tax tokens were used in Colorado from September 1, 1935, to February 28, 1945. They were generally 2-mill (1/5 cent) tokens, as the state tax rate was 2 percent.
Tax tokens were used to pay fractional taxes when a purchase was too small to be taxed as a whole cent.
Sales of less than 5 cents were not taxed. Purchases of 6 to 14 cents required one token, 15 to 24 cents required two tokens, and so on.
Tokens were originally made of aluminum, but cheaper plastic was later used.
Colorado has produced aluminum, red fiber, and red plastic tax tokens. They are all very common and cost less than a dollar.
