5 000 000 000 000 Mark Reichsbanknote

By the time this note entered circulation in late 1923, the Reichsbank was issuing denominations that would have been unimaginable twelve months earlier. The five-trillion-mark note is one of the final gasps of the hyperinflation series — printed as the exchange rate against the dollar was collapsing through the billions per mark, with new notes being rushed out faster than ink could dry. The Reichsbank itself acknowledged that printing could not keep pace with demand; at the peak, over thirty paper mills and nearly a hundred printing firms across Germany were contracted to produce currency.

The stabilization came with the introduction of the Rentenmark on 15 November 1923, at a conversion rate of one Rentenmark to one trillion old marks — making this note worth precisely five Rentenmark when redeemed.
