100 Escudos

The Banco de España's 1870 issue came at an awkward political moment: the Glorious Revolution of 1868 had ousted Isabel II, and Spain was mid-experiment with a constitutional monarchy under Amadeo I. The escudo had itself only been introduced in 1864 to replace the real, and by 1871 it would already be superseded by the peseta — meaning this note's denominated unit was obsolete within roughly a year of issue.

Short-lived currency units tend to produce short print runs with low survival rates, and the escudo series is no exception. Notes that actually circulated through those chaotic transitional years rarely emerge intact.
