150 Scudi

The Sacro Monte della Pietà di Roma was one of the oldest institutional pawnbrokers in Europe, founded in 1539 to provide low-interest loans to the poor as an explicit counterweight to moneylending. By the late eighteenth century it had evolved into a quasi-banking institution operating under papal authority, issuing cedole — bearer certificates functioning as paper money — backed by deposits of pledged goods and precious metals held in its Roman vaults.

The 150 Scudi denomination sits at the upper end of the cedole range, suggesting use in merchant and institutional transactions rather than everyday commerce. Papal financial instruments of this period were deeply shaken by the French Revolutionary Wars of the 1790s, and large-denomination notes from just before that disruption survive in genuinely limited numbers.
