25 000 000 Drachmai Kalamata

By mid-1944, the Axis occupation had so thoroughly destroyed the Greek monetary system that the Bank of Greece authorized regional branches to issue their own emergency notes. The Kalamata branch was among those that produced local overprints and stamps on existing notes to meet catastrophic hyperinflation — the same inflation that would, within months, require denominations in the trillions of drachmai.

The official stamp is the sole security feature, which reflects both the desperate improvisation of the period and the near-total collapse of centralized monetary control. Authentication of genuine branch stamps versus later forgeries remains a known complication with this entire regional emergency series.
