1/2 Kreuzer - William I

William I had assumed the Württemberg throne in 1816 following the death of his father Frederick, inheriting a kingdom whose currency was a fractured mess of pre-Confederation coinage, Napoleonic-era issues, and locally circulating scrip. The 1818 billon issues were part of a systematic recoinage effort to regularize Württemberg's monetary circulation under the new reign — a mundane administrative act, but one that consumed considerable mint resources in Stuttgart through the late 1810s.

The .104 fine silver content places this squarely in the degraded billon range typical of German petty coinage of the period, valued more for token convenience than intrinsic metal.
