10 000 Leva

Bulgaria's 1997 hyperinflation was among the most severe in post-communist Europe — the lev lost roughly half its value each month at the crisis peak, and denominations climbed so fast that a 10,000 lev note, unthinkable just years earlier, was ordinary spending money by mid-year. The Bulgarian National Bank lost control of monetary policy so completely that the government was forced to introduce a currency board in July 1997, pegging the lev to the Deutschmark at 1,000:1 and effectively surrendering independent interest rate policy.

This note was printed before the redenomination that followed, making it a direct artifact of the collapse rather than the recovery. The 1,000:1 conversion meant 10,000 leva became exactly 10 new leva — a ratio that underscores just how far the currency had deteriorated.
