2 000 000 Mark Gewerkschaft Sophia-Jacoba

Sophia-Jacoba was a coal mining operation in the Heinsberg district, and like hundreds of German industrial concerns in the summer of 1923, it issued its own emergency currency — Notgeld — to meet payroll when the Reichsbank simply could not supply enough physical banknotes to keep pace with hyperinflation. The 2,000,000 Mark denomination places this squarely in the late-inflation phase, when denominations that would have seemed absurd in January were routine by August.

Hermann Schött A.G. in Rheydt handled a significant volume of commercial printing work for Rhenish businesses during this period, which made local sourcing both practical and fast — speed mattered far more than prestige when a note's purchasing power could halve within a week of printing.
