History & Notable Facts
The 25 Centimos coin from Alfonso XIII's reign featured a portrait of the king that aged with him, from a young man in 1904 to a more seasoned figure by 1931.
That design choice reflected the era's political instability, with the coin struck in copper-nickel to withstand everyday use. Minting occurred primarily in Madrid, though records don't specify exact outputs for every year—some details burned up in the 1936 Spanish Civil War archives fire. Variations exist in the obverse details, like subtle changes in the king's effigy, which can trip up even seasoned collectors.
I once mistook a 1910 variant for a rarer issue. It wasn't.
