500 000 Roubles

Transnistria's 1997 high-denomination paper issues emerged from one of the more peculiar monetary situations in post-Soviet history. The Pridnestrovian Moldavian Republic was — and legally remains — an unrecognized state, meaning its currency had no standing in international exchange markets and circulated purely by local administrative fiat. The 500,000 rouble figure reflects the inflationary spiral that followed the introduction of the Transnistrian rouble in 1994, itself a replacement for provisional coupon money.

The series was short-lived. A redenomination in 2000 replaced these notes at 1,000,000 old roubles to 1 new rouble, effectively wiping out the face value entirely.
