There were two companies involved in construction of the Suez Canal which issued tokens in 1865: Borel Lavalley and Ch.& A.Bazin. There was also a Societe Cooperative du Canal de Suez bases in Ismailia which issued tokens in 1892. In higher grades all these are pretty scarce. Here are a few samples from my collection:

I have a 1942 Vichy Franc which is 1,9 mm thick and a 1944 Vichy Franc only 1,5 mm thick. When put together one can easily see the difference in thickness.
