Alfonso XII 10 Centimos

The Alfonso XII 10 Centimos coin was struck using a bronze alloy that included significant amounts of tin, making it more durable than earlier Spanish coppers that often crumbled in circulation.

That durability came in handy during Spain's economic turbulence in the late 19th century, as these coins saw heavy use in everyday transactions. The obverse shows a profile of the king, complete with his characteristic mustache, while the reverse features the Spanish coat of arms—a design choice that reflected the monarchy's attempt at normalcy after years of chaos. Mintage figures vary by year, but records from the Madrid mint are spotty; we know production peaked around 1880, though exact numbers were lost in bureaucratic muddles.

As for restored examples, like this one, they've been cleaned of verdigris and patina, revealing the original reddish hue. It's a bit like finding an old letter in a trunk—still readable, but you wonder what stories the stains told.
