2 Thalers / 3½ Gulden - Henry XX

Henry XX ruled Reuss-Greiz from 1818 until his death in 1859, presiding over one of the most administratively peculiar states in the German Confederation — a principality so small it covered barely 300 square kilometers yet maintained full coinage rights. The 2 Thaler denomination was introduced across German states following the Dresden Convention of 1838, which standardized the double thaler as a common large silver piece interchangeable across member states, effectively making this coin legal tender far beyond Reuss-Greiz's own borders.

The Reuss family's naming convention — all male heirs bore the name Heinrich, numbered sequentially across centuries — meant Henry XX was the twentieth Heinrich in an unbroken dynastic line stretching back to the 12th century.
