10 000 000 000 000 Mark Reichsbanknote

By the time this note was authorized, the hyperinflation it nominally addresses had already collapsed. The 10 trillion Mark denomination belongs to the final phase of the crisis series — issued in early 1924 as the Rentenmark stabilization was already taking hold, meaning most of these saw little genuine transactional use before becoming worthless under the conversion. The Reichsbank was still producing paper denominated in the old Mark while the economy had effectively abandoned it.

At 1.2 billion to the U.S. dollar in November 1923, even this figure was barely functional for daily purchases. The conversion rate to Rentenmark was fixed at one trillion old Mark to one new unit.
