1 Peso overprint on P#S131 - Banco de José Bunster

In the late 1890s, Chile's government exercised its right to overprint existing private bank stock as fiscal currency — a pragmatic solution to chronic note shortages that required no new engraved plates. The Bunster bank base note (P#S131) was already in circulation when the Treasury commandeered unissued remainders for this purpose.

The ABNC connection here is incidental to the overprint itself, which was applied in Chile. Collectors frequently misattribute the full production to New York; the American Bank Note Company printed the original Bunster plates, but the fiscal overprint conversion happened domestically.
