The Banque de l'Indo-Chine was chartered in 1875 by the French government specifically to finance colonial commerce and to displace the mixture of Chinese, Mexican, and Spanish silver coin then circulating across the region. This note came out of that founding mandate — the dual denomination in dollars and piastres reflects genuine monetary uncertainty on the ground, where traders in Saigon, Hanoi, and Phnom Penh were still quoting prices in multiple systems simultaneously.
