Tolar (German: Thaler) or Jáchymovský tolar is the Czech name for the silver coin minted in Kingdom of Bohemia from 1520 until 1672 in Jáchymov (German: Joachimsthal). On obverse of the coin is depicted Saint Joachim with coat-of-arms of the noble family Schlik, who founded the mint in Ore mountains, with titles of brothers Schlicks in inscription:"STEPHANI:ET:FRATRVM: COMITVM:DE:BASSANO" (without abbreviations). On reverse side is depicted the crowned Bohemian lion with title of the Bohemian King Louis of Jagiellonian dynasty: (without abbreviations):"LVDOVICVS DEI GRACIA REX BOHEMIAE".

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 silver currency in Bohemia from 1520 to 1750.^[1]
