20 Escudos 1891

I'm not entirely sure about a gold 20 escudos coin dated 1891, as Portugal's escudo currency wasn't introduced until 1911. That said, the Lisbon mint did produce gold coins during the monarchy under King Carlos I, likely including denominations like the 5,000 or 10,000 reis around that time. These were struck in 0.900 fine gold and featured the king's portrait, reflecting the era's royal iconography. Mintage records for specific years are spotty, possibly destroyed in fires or bureaucratic shifts. If this is a confusion with those reis coins, they represent straightforward examples of late 19th-century Portuguese currency. Worth noting, though, that values fluctuated with global markets, much like today.
