1/2 Thaler - Maria Theresia Graz

Maria Theresia's monetary reforms of the early 1750s were driven partly by the financial strain of the War of Austrian Succession, which had nearly bankrupted the Habsburg treasury. The Graz mint — Münzstätte Graz — was one of several provincial facilities pressed into service to meet the demand for standardized silver coinage as Theresia worked toward the Conventionsthaler agreement of 1753, which established a common monetary standard with Bavaria and brought the chaotic proliferation of regional coinages under tighter imperial control.

The four-year production window at Graz for this type closed well before the mint itself ceased silver operations entirely later in the century.
