100 Colones

The Banco Internacional de Costa Rica was the country's state bank, established in 1914 — the same year this note was issued — replacing the earlier Banco de Costa Rica as the government's primary financial institution. The timing was not coincidental: the reorganization was driven partly by concerns over monetary discipline and centralized control that had been building since the 1900s coffee export boom left private banks overextended.

American Bank Note Company's involvement was typical for Central American state banks of the period, but the P#164 is among the earliest issues from this new institution, making surviving examples genuinely early in the series.
