Argentina replaces its currency five times
Between 1970 and 1992, Argentina replaced its currency five times, each time removing zeros and starting over: peso (1970-1983), peso ley (1983-1985), peso argentino (1985-1985 — lasted 19 months), austral (1985-1991), and finally the convertible peso (1992). Each currency ended because accumulated inflation had made the denomination unmanageable. Across all five currencies, the cumulative depreciation of Argentina's money against the U.S. dollar was roughly 10^13 — ten trillion to one. The Convertibility Plan of 1991 pegged the new peso 1:1 to the dollar and stabilized prices for a decade, but collapsed in the 2001-2002 crisis.
Each redenomination took several zeros off the currency, which briefly disguised the cumulative damage. An Argentine who held the same dollar-equivalent savings through all five currencies would have seen their nominal peso holdings expand by a factor of 10^13 while their real purchasing power fell dramatically.

With gold constraints gone entirely, currency debasement became a recurring feature of emerging-market economics. Argentina replaced its currency five times between 1970 and 1992, each time lopping off zeros and re-starting. Brazil did similar serial redenominations. Yugoslavia, Zimbabwe, and the post-Soviet states produced spectacular hyperinflations. Meanwhile, major central banks learned to hide their monetary expansion in increasingly technical mechanisms — money-supply measures were redefined, reporting requirements were relaxed, and the Federal Reserve stopped publishing M3 entirely in 2006.
