Also found in: Encyclopedia, Wikipedia.
A 16th-century name for Jachymov, a town in what is now the Czech Republic that was known for its silver deposits. Coins minted from silver found in Joachimsthal became common throughout the Holy Roman Empire and elsewhere. This coin was called the Joachimsthaler, which was shortened to thaler. This in turn became the origin for the word "dollar."
