50 Mark

The Internationale Bank in Luxemburg was established in 1856 and operated as one of the Grand Duchy's primary commercial banks during a period when Luxembourg's monetary situation was genuinely complicated — the country used both Belgian francs and German marks interchangeably, reflecting its dual economic pull toward both Brussels and Berlin. A mark-denominated issue from a Luxembourg bank at the turn of the century signals orientation toward the German customs union, the Zollverein, of which Luxembourg remained a member until 1919.

Giesecke & Devrient had been printing high-security banknotes from Leipzig since 1852 and were the dominant continental supplier by 1900. Pick 5 is among the scarcer pieces from this issuer; the bank was absorbed and its note-issuing rights extinguished well before World War One disrupted the region entirely.
