Following Spain’s unification, the peseta became the official currency in 1868, influenced by the Latin Monetary Union. It remained in use until the introduction of the euro in 2002. Peseta coins were minted in denominations of 1, 5, 25, 50, 100, and 500 pesetas, reflecting the country's evolving economic conditions over time.
Spain adopted the euro (€) on January 1, 2002, joining the Eurozone. The first series of euro coins featured the Cathedral of Santiago de Compostela on the 1, 2, and 5 cent coins, the profile of Miguel de Cervantes on the 10, 20, and 50 cent coins, and King Juan Carlos I on the €1 and €2 coins until 2014, when he was replaced by King Felipe VI.
The 1, 2, and 5 cent coins are made of copper-plated steel, while the 10, 20, and 50 cent coins are composed of Nordic gold. The 1 and 2 euro coins are bimetallic. Spain also occasionally issues commemorative euro coins, often honoring significant historical events or figures.
