2 1/2 Euros Earrings of Viana do Castelo, gold

Portugal's "Ourivesaria" series, launched in 2013, commemorates regional goldsmithing traditions that remain living craft practices rather than historical curiosities. The earrings of Viana do Castelo — filigree pieces worn as part of the Minhota folk costume — represent one of the most recognizable forms of Portuguese popular jewelry, still produced by hand in the Minho region by artisans working techniques passed through family workshops across generations.

The bimetallic construction mirrors the actual earrings' combination of materials, a deliberate curatorial decision by INCM that distinguishes this series from straightforward commemoratives.
