Maria Theresa pendant , Ethiopia 02.04.1429
Maria Theresa had her first thaler minted in 1741, and took great pains to secure its value. She signed one of the first international coinage conventions in 1753, which defined its silver content and set exchange rates. This ensured it would become a stable currency for international trade. In fact, it enjoyed a success she could hardly have imagined when she died in 1780. By then, the Habsburg mints had struck over 30 million thalers. (The MTT by Richard Armstrong).
