Chile's 1880s note issues came during a period of serious monetary instability — the War of the Pacific (1879–1884) against Peru and Bolivia had stretched public finances badly, and paper money circulated under effective inconvertibility. The government had suspended specie payments in 1878, and notes issued through this period floated on uncertain backing.

The American Bank Note Company held a long relationship with Chilean authorities across multiple series. P#12B is a sub-variety within the broader 12 series, distinguished by signature or date combinations rather than a redesign — collectors should verify the specific signing configuration against reference plates, as the sub-varieties are frequently mislabeled in trade.
