10 Gulden

The Wiener Stadt Banco was not a bank in the modern commercial sense — it was a municipal credit institution founded in 1706, originally tasked with managing Vienna's civic debt. By the early nineteenth century it had become the principal issuer of paper currency in the Habsburg lands, a function it performed under increasing strain as the Napoleonic Wars drained imperial finances at an alarming rate.

The 1806 series appeared just one year before Austria's catastrophic state bankruptcy of 1811, when the government's Finanzpatent reduced the face value of all outstanding Banco notes to one-fifth. A 10 Gulden note issued in 1806 would have been legally worth 2 Gulden by the following decade.
