Biberach an der Riß was one of hundreds of German municipalities forced to print their own emergency currency in 1923 as hyperinflation outpaced the Reichsbank's ability to supply usable denominations. A billion marks — one Milliarde — was not an extraordinary face value by late 1923 standards; notes of this denomination were often spent within hours of issue before their purchasing power evaporated further.

Julius Baur designed the note locally, and Dr. Karl Höhn printed it in town — an entirely domestic production with no involvement from the major specialist printers like Giesecke & Devrient who handled Reichsbank output. That local printing chain is worth noting: quality control varied, and Höhn's presswork on the Biberach series is considered competent but uneven across the run.
