5 Euros The Unicorn, gold

Part of Portugal's ongoing "Animals of the Portuguese Coat of Arms" series, this issue takes the heraldic unicorn — one of the shield's two supporting figures inherited from medieval armorial tradition — as its subject. The series has drawn sustained collector interest precisely because it commits to the full set of charges and supporters rather than cherry-picking the obvious ones.

At 15.55 grams of .999 gold, the nominal five-euro face value is purely ceremonial. Mintage for the gold variant was tightly capped, as is standard for Casa da Moeda's bullion-adjacent collector issues in this format.
