The word dollar came from the Bohemian mining town called Joachimsthal.
In the 16th century, the government opened its mint near a source of metal ores there, so the coins that came from it were known as Joachimsthalers.
Over the years, wind, rain, and vernacular usage eroded the name down to thaler or taler in Danish and Norwegian.
The English heard it as “dollar,” and a new word was coined, no pun intended.
Eventually, the coins minted at Joachimsthal soon lent their name to other coins of similar size and weight such as the Dutch lion dollar, circulated throughout the Middle East.
By the mid 18th century, the lion dollar was replaced by the Spanish “pieces of eight” which were common in the Thirteen Colonies during the American Revolution.
Spanish dollars were even legal tender in one colony, Virginia.
