This month marks 80 years since Hungary introduced the forint on August 1, 1946, ending the pengő’s historic collapse.

The conversion rate was astonishing: one forint replaced 400,000 quadrillion pengő—effectively wiping 29 zeros from the old currency. Today, surviving pengő notes give collectors a tangible glimpse into the most extreme hyperinflation era in monetary history.
