28 Centavos Fuertes = 2 Chirolas

The denomination itself explains everything. "Chirola" was Rio de la Plata slang for the old medio real coin, and the 14-centavo unit it represented was a deeply embedded piece of small-change arithmetic that lingered in popular reckoning long after decimalization had officially made it obsolete. Two chirolas equalled 28 centavos fuertes, and the Banco Nacional had to issue this note because nobody could keep small silver in circulation — it was hoarded, clipped, and melted the moment it appeared.

Guillermo Kraft signed as inspector as well as printer, which is an unusual concentration of authority for a note of this type. His Buenos Aires press was a dominant force in Argentine commercial printing through the 1880s, and the in-country production avoided the delays and currency risks of commissioning from European security printers.
