10 000 000 000 Mark

Rastatt's 10-billion Mark Notgeld dates from the peak weeks of the German hyperinflation, when municipal authorities across Baden were issuing emergency currency faster than the Reichsbank could supply denominations large enough to be useful. Arthur Albrecht & Cie. in Karlsruhe handled a considerable volume of this regional emergency work in 1923, producing notes for multiple southwest German municipalities under severe time pressure.

The watermarked paper is worth noting — by late 1923 many Notgeld issuers had abandoned security features entirely as pointless given the velocity at which denominations became obsolete. That Rastatt retained it suggests either advance ordering or a printer with stock already on hand.
