Episode notes
Dollar Name Came From A 16th Century Bohemian Coin
- The word dollar predates the United States and comes from a 16th-century Bohemian coin called the Joachimstaller that spread across Europe.
- Brendan Greeley explains Spanish Reales de Ocho matched the Joachimstaller's weight, so English speakers simply called the widely circulated piece of eight a dollar.
Jakomstall Mine Hustle Spawned A Trusted Coin
- Count Stefan Schlick secretly exploited a silver deposit at Jakomstall and was forced to mint uniform high-quality coins to appease authorities.
- Those small but valuable Jakobstallers became trusted across Northern Europe, used by nobles, merchants, and eventually miners demanding payment in them.
Consistency And Volume Made The Dollar Useful
- The Joachimstaller's key innovation was consistent purity, size, and volume, which let people count rather than weigh silver, driving broad adoption.
- Brendan Greeley notes miners, merchants, and states began copying and calling their own versions 'dollars' because the coin was so useful.
