Etymology

The word "dollar" traces back to the "Joachimsthaler," a coin named after the silver mines of Joachimsthal. Over time, "thaler" evolved into "dollar" through Dutch ("daalder") and English adoption. The term became globally prominent with the rise of the Spanish peso (also called "dollar"), which influenced the U.S. currency system.
