Unidentified Pendant And Coin/ Token (Id: French WWI Medal And Spade Guinea Token)

@jam, it is always better to start a new thread for each separate item so that we can give them all the attention that they deserve. With that said, I wonder if the badge/medal in the top isn't celebrating a victory over the Germans. It kinda looks like the guy with the rifle is holding up a captured pickelhaube.

The archway behind the soldier looks very much like the Arc de Triomphe in Paris.

The style of the soldier's uniform is French, but could be that of a nation inspired by French military fashion, eg Belgium. He is wearing a helmet and puttees. The Adrian helmet was introduced in mid 1915. Before that standard headgear was a kepi.

This could easily represent a French soldier from around 1915 to 1940. I suggest around 1918-19 is more likely, firstly because of the victory-style pose, and secondly because in his left hand he is holding as a trophy what appears to be a German spiked helmet called a "pickelhaube". This helmet was replaced in 1916 front line service by the stahlhelm, but remained in public thought as a symbol of Germany and Prussia.

The first battle of the Marne was in September 1914. At that time French infantry wore the kepi and gaiters. The second battle of the Marne was in 1918. The appearance of the soldier fits the second battle. From the kit on the belt the uniform is fairly generic, which suggests the artist wasn't producing an accurate replica, more a general impression. It could well be celebrating the first battle but produced a little while afterwards.

What makes you think it commemorates the battle of the Marne?
