5 Euro Herrera de la Mancha

Prison scrip issued by a Spanish penitentiary is unusual enough, but the involvement of the Fábrica Nacional de Moneda y Timbre — the same state body that prints official Spanish currency and passports — makes this note genuinely remarkable. FNMT produced it to the same security standards applied to public circulation notes, a deliberate choice given the obvious counterfeiting risks inherent in closed-economy scrip.

Herrera de la Mancha, located in Manzanares, Ciudad Real, is a high-security facility. Internal currency of this kind was used to allow inmates to purchase goods within the prison economy while preventing the movement of real currency inside the walls.
