20 Décimos

The Banco Nacional was one of several short-lived private banking experiments in the early Spanish American republics, and most of its note issues never achieved meaningful circulation before the institution collapsed or was absorbed. A 20 Décimos denomination is a fractional unit suggesting this issue was aimed at retail transactions rather than interbank clearing — politically ambitious for an institution with no track record of public trust.

1826 places this squarely in the post-independence monetary chaos common across the region, when new governments struggled to establish fiduciary credibility. PS# prefix indicates a private, non-governmental issuer per the Standard Catalog classification.
