The Maria Theresa Thaler 1780
One month ago I found the thaler on the field which was firstly cointed during the reign of Maria Theresia.This coin was widely used as a business coin over the 200 years, especially in Africa and arab countries. This thaler was cointed in many mints all over the world. The weight if this thaler is 28 grams of nearly pure silver. Unfortunately the mint of this specific coin I did not find.
