Tolar (German: Thaler) is the Czech name for the silver coin mined in Bohemia in 16th century in Jáchymov (in German: Joachimsthal). The modern word dollar was derived from the Spanish dollar, so-called in the English-speaking world because they were of similar size, and weight to the German Thalers. The German Thalers were so named because they were first minted from a silver mine in 1520 in Joachimsthal. It was the main currency in Bohemia from 1520 to 1750.
