350 Lire - Cassa di Risparmio di Trento e Rovereto

Italian savings banks were permitted to issue local fiduciary notes — fedi di credito — during the chronic coin shortage of the 1970s, when the Italian state couldn't produce enough small-denomination coinage to meet everyday demand. These circulated as functional substitutes for coins in shops and markets within the issuing institution's immediate area, essentially a private solution to a public infrastructure failure.

The 350 lire denomination is among the more unusual values to appear in this series — an odd figure that reflects the specific change-making gaps retailers needed to fill rather than any round-number convention. Tipolitografia Stampa Rapida, a local Trentino commercial printer, handled production, which was entirely normal for these issues: no security printer involvement, no intaglio.
