500 Francs

The Banque de Madagascar et des Comores was itself a transitional institution — established in 1950 to replace the Banque de Madagascar, it was absorbing the Comoros into its mandate even as both territories were moving toward independence. Madagascar left the franc zone arrangement in 1963 when the Malagasy Franc was nationalized under the newly formed Banque Nationale Malgache, which effectively ended this note's official life.

Clément Serveau designed extensively for French colonial currency throughout the mid-twentieth century, and Robert Armanelli was among the more accomplished intaglio engravers working at the Banque de France during this period. The three signature combinations — all pairing a rotating first signatory with Gonon as the consistent countersignatory — allow for reasonably precise dating within the 1960–1963 window.
