1 Rentenpfennig

The Rentenpfennig was born directly out of monetary catastrophe. When hyperinflation peaked in late 1923 — the dollar briefly exchanged at over four trillion Marks — Germany introduced the Rentenmark as an emergency currency backed notionally by agricultural and industrial land. These bronze pfennig denominations followed immediately, circulating alongside the new paper issues as the first physically stable coinage Germans had handled in years. The psychological weight of that stability should not be underestimated; ordinary transactions had become nearly impossible with paper alone.

Production ran across multiple mints through 1929, leaving a range of mintmark varieties under the KM#30 designation that reward closer attribution.
