2026-M S€10 / 8R Silver, Queen Isabella I of Castile PR DCAM

A ten-coin program issued by the Royal Spanish Mint to mark the 250th anniversary of the independence of the United States, and to put on record the decisive part Spain played in it — from the campaigns of Bernardo de Gálvez on the Gulf Coast to the Spanish milled dollar that became the model for the first American dollar. Three coins were released in 2025 and seven in 2026.
