10 Rentenpfennig

The Rentenmark system, introduced November 1923, was an emergency monetary framework backed fictitiously against agricultural and industrial land — a political fiction that nonetheless worked. The Rentenpfennig subdivisions were struck in aluminium bronze partly because the metal carried no meaningful intrinsic value, insulating the new currency against the commodity speculation that had destroyed the Papiermark. Coins dated 1923 are scarce in practice; production at that year's end was limited, and the bulk of this type entered circulation through 1924.
