20 Reales - Isabel II

These small gold pieces were struck during the final, turbulent stretch of Isabel II's reign, when Spain's finances were under severe strain from colonial commitments and recurring domestic instability. The 20 reales denomination itself was short-lived — the reales system was abolished in 1864 when Spain decimalized its currency, making this type a creature of the monetary transition rather than a settled coinage tradition.
