10 Réis - Luíz I

Portugal's bronze coinage of this period was struck primarily at the Lisbon mint (Casa da Moeda) during a reign defined more by constitutional stability than by monetary drama. Luís I had ascended in 1861 and presided over a relatively uneventful monetary administration — these small bronze pieces fulfilled everyday transactional needs during a period when Portugal's Atlantic trade remained significant but its imperial revenues were increasingly strained.

The Gomes reference places this squarely within a short emission window that closed with Luís I's death in 1889.
