Vintém - Pedro II Porto mint

The vintém — nominally valued at 20 réis — was among the smallest silver denominations in regular Portuguese circulation, and the Porto mint's output during this period reflects the crown's effort to maintain provincial coining capacity during the reign of Pedro II. Portugal's monetary system in these years was under sustained pressure from wartime expenditure tied to the War of the Spanish Succession, which Pedro entered in 1703 by signing the Methuen Treaty with England, committing Portuguese silver to an alliance that would reshape Atlantic trade for generations.

Porto struck in smaller volumes than Lisbon, and survivors attributable to this mint are correspondingly scarcer in the market.
