25 Pesetas Wedding of Alfonso XIII and Victoria Eugenie

Struck to commemorate the May 1906 wedding of Alfonso XIII and Victoria Eugenie of Battenberg, the ceremony itself was interrupted when anarchist Mateo Morral threw a bomb concealed in a bouquet of flowers at the royal carriage in Madrid's Calle Mayor. Over twenty people were killed; the couple survived. This coin was already in production or circulation when the attack occurred.

The nickel-zinc composition marks a departure from Spain's earlier silver coinage and reflects the fiscal constraints of a monarchy already losing its grip on imperial revenues following 1898.
