re: Help identification: French colonies commun use
It is pretty clear that the surcharge is over the cancellation, so the surcharge is bogus or forged. (or part of another postal marking, like postage due or such.)

re: Help identification: French colonies commun use
Hello Jacques,
I collect French colonies and do have some helpful literature. According to Stone's "Alphabetical list of post office names and other words in postmarks used on the general issues of French colonies 1860-1892" (New York, 1978), the postmark Saigon-Cal./Cochinchine is known in the years 1887 through 1892 and possibly later. The post office using this mark operated from 1887 to 1893.
Not only does a 10 on 15 overprinted stamp not exist among stamps from Cochinchina (or later Indochina), but it is altogether bogus, meaning it does not exist from ANY colony.
Generally, the "nameless stamps" from the French Colonies are difficult, because these are stamps from the general issue that were issued with overprinted value in certain colonies and are listed under these colonies. Two sources I consulted, Aretz and Michel, both confirm that no 10 on 15 was created for any colony. In fact the 15c denomination was the one most commonly CREATED by overprinting on other denominations. The only '10' on any of the Dubois stamps (but not the 15c value) was issued in Senegal.
