Jáchymov

 town, spa resort

The place were the word "dollar" originated.
The Joachimsthaler coins minted there in the 16th century became know as thaler for short, with Dollar and similar words for monetary units in many languages deriving from it.
The German name Thaler came from the Bohemian coin minted from the silver from a rich mine at Joachimsthal — Jáchymov (St. Joachim's Valley) in Bohemia north of Karlovy Vary (Karlsbad). Not long after issuance, these coins gained the name Joachimsthalers. From there, coins gained the name "thaler" regardless of the issuing authority.[1] The name is historically related to the tolar, in Germany Reichsthaler, Slovenia (Slovenian tolar) and Bohemia, the daalder in the Netherlands and daler in Sweden, Denmark, and Norway
