Thaler
1. South German: topographic name from Middle High German tal ‘valley’ + the suffix -er denoting an inhabitant. 2. Germanized form of Slovenian surname Dolar, a topographic name for someone who lived in a valley, from dol ‘valley’, a word of German origin.
Although we use the English pronunciation with a "th", it was probably originally pronounced like"dollar" but with a "ta"
