1/2 Scudo `Obses` Siege of Mantua

Mantua's 1630 siege was among the most catastrophic episodes of the Thirty Years' War on Italian soil. Imperial forces under Ferrante II Gonzaga had besieged the city, and the ducal mint — operating under desperate conditions — struck obsidional coinage from whatever debased metal was available. The word obses itself means hostage or pledge, a pointed declaration that the coin was backed by the city's future rather than its present reserves.

The plague that swept through Mantua concurrent with the siege killed an estimated two-thirds of the population. Coins struck in this window circulated in a city already collapsing.
