Southeast Asian colonial banknotes have become a major category for Asian collectors over the past decade. The 100-piastres notes of French Indochina are the category’s flagship type.

What it is

The Banque de l’Indochine issued 100-piastres notes for circulation in French colonial Vietnam, Laos, and Cambodia from 1925 to 1951. The notes are large, high-denomination, and were printed in Paris with the same security features used for French metropolitan currency. Each issue features ornate allegorical figures representing French colonial themes; the 1939 “blue dragon” type and the 1947 “Angkor” type with the Cambodian temple imagery are particularly sought after.

What drives value

Condition (notes that circulated in tropical conditions are rarely better than VF), serial number desirability (low numbers, replacements, specimen overprints), provenance from documented Bank of Indochina archives, and the original 1925-issue large-format notes versus the smaller 1939 and 1947 redesigns. PMG and PCGS Banknote both grade Indochinese notes; the major dealers are Smythe, Stack’s Bowers Hong Kong, and the Spink Hong Kong office.
