1 000 000 000 000 Mark Reichsbanknote

By the time this note entered circulation in late 1923, the Reichsmark's collapse had become so extreme that even trillion-mark denominations were functionally inadequate within days of issue. The Reichsdruckerei was printing around the clock, and the government had authorised hundreds of emergency printers — Notgelddruckereien — across Germany to supplement output, though the Reichsbank's own trillion-mark series remained centrally produced in Berlin.

The stabilisation came on 15 November 1923 with the introduction of the Rentenmark at a rate of one trillion paper marks to one. Notes like this were rendered worthless almost immediately after printing, which paradoxically means many survived unspent in large quantities.
