10 Pesos

Argentina's provincial quasi-currency boom of the early 2000s is one of the stranger episodes in modern monetary history. Facing a severe liquidity crunch under currency board constraints that pegged the peso one-to-one with the US dollar, provincial governments began issuing their own interest-bearing bonds denominated in pesos and designed to circulate as cash. Tucumán's series — known locally as "Bocade" notes — was among dozens of such emissions from different provinces, all technically debt instruments but functionally paper money.

The federal government eventually forced their withdrawal after the 2001–2002 collapse, when the convertibility regime itself fell apart. Redemption was uneven across provinces.
