1937 Germany 2 Rentenmark Banknote P# 174b Grades Choice AU/BU Slider. The "Rentenmark" was issued in 1923 to help stop the hyperinflation in Weimar Germany after the "Paper Mark" had become worthless. Unlike the Goldmark, which was backed by gold, or the Papermark, which lacked the backing of a commodity, the Rentenmark was backed by the land used for agriculture and business. The Act creating the Rentenmark backed the currency by means of twice yearly payments on property, due in April and October, payable for five years. Although the Rentenmark was not initially legal tender, it was accepted by the population and its value was relatively stable.
