2 Korona Metro Vízmérőgyár Rt., Budapest

Metro Vízmérőgyár Rt. was one of dozens of Budapest industrial firms that issued their own small-denomination paper notes during the acute coin shortage that gripped Hungary in 1920. The National Bank simply could not keep fractional coinage in circulation — metal had been hoarded, exported, or consumed by wartime production — so factories, cooperatives, and municipalities printed their own scrip to make change for workers and canteen purchases. These emergency issues were technically illegal tender outside the issuing firm's own premises.

The Adamo catalog documents several denominations from this issuer; the 2 Korona sits in the middle of the series.
