100 Colones

Banco Anglo Costarricense was not a state bank but a private British-linked commercial institution operating under Costa Rican concession — one of several competing banks of issue that circulated their own notes freely before the Banco Internacional de Costa Rica absorbed the right of issue in 1914. This note therefore predates centralized monetary control entirely, existing in a period when multiple private banks could legally create circulating currency.

The American Bank Note Company printed the series from its New York facility. At this denomination, genuine circulation would have been limited to large commercial transactions — 100 Colones was serious money in early twentieth-century Costa Rica, and surviving examples show comparatively little wear for that reason.
