Sales tax tokens (and other exonumismatic and philatelic pieces used in the process of collecting sales taxes) were used in several states, primarily in the Midwest, South, and Southwest, in the 1930s and 1940s. Although in some cases they were legal until the early 1960s, for the most part they were discontinued shortly after World War II.

Except for occasional political pieces opposing a proposed sales tax in one of the few states still lacking one, the collecting field is closed in the sense that no more tokens are being issued and none are in public circulation. However, there continue to be new discoveries of unknown pieces, major die varieties, a wide variety of historical materials, and other items.
