5000 Réis - Luiz I

Portugal's gold coinage was reorganized under the 1854 monetary reform that tied the milréis to a decimal system and aligned the country broadly with emerging European bimetallism. The 5000 réis denomination sat at the practical upper end of daily commerce — large enough to matter, small enough to actually change hands. Luiz I had acceded to the throne in November 1861 following the sudden death of his brother Pedro V from typhoid, and the 1862–63 issue was among the first coinage struck in his name.

The Gomes L1 15 reference distinguishes date varieties within this short two-year run.
