100 Pesetas - Provisional Government Pattern, copper

Spain's Provisional Government, which had deposed Isabel II in the Glorious Revolution of 1868, commissioned a sweeping coinage reform that introduced the peseta as the national unit. Pattern strikes in copper were produced in 1870 to test designs and denominations before committing to silver or gold production — the 100 pesetas value was never intended for copper circulation at any point.

Aureo references 42–44 indicate at least three distinct die combinations documented for this type, a density of variety unusual for what was essentially internal mint documentation.
