XX Réis - Pedro V Countermarked with 'Small Crown'

The small crown countermark applied to these circulating copper pieces was a practical response to chronic coin shortages across Portugal's Atlantic island territories in the mid-nineteenth century. Rather than ship new coinage, Lisbon authorized the remarking of existing currency to confirm local validity — a recurring administrative workaround in São Tomé and Príncipe, where the cost of a dedicated colonial mint was never justified by the islands' small population.

Pedro V was still a minor when the countermarking program was sanctioned, ruling under the regency of his mother Dona Estefânia's predecessor arrangements — the logistics of colonial currency authorization running well ahead of the young king's formal reign.
