450 Réis Countermark 'PM' over 1 Rupee/German East Africa

Portuguese colonial administrators in Mozambique faced a persistent shortage of small silver coinage during the late nineteenth century, and rather than wait for new issues from Lisbon, they authorized the countermarking of foreign silver already circulating in the territory. The German East Africa rupee — the coin beneath this mark — was legal tender in the adjacent German colonial zone and crossed the border freely through trade networks along the coast and interior routes.

The 'PM' punch, standing for *Provincia de Moçambique*, revalued the piece at 450 réis for local circulation. Countermarked issues of this type were applied across multiple host coins of compatible weight, making die-match attribution to specific punching batches genuinely difficult.
