Rare Robert-Houdin Magic Token Help Needed

I was contacted by Paul Courville, a collector of magicians tokens,  concerning an item he has acquired of Robert-Houdin. Specifically, he is searching for any information or individual with information that could provide him with additional details about the item.

Paul found a reference for this coin dating it to France 1935, created by J Dhotel, however, the listing says the back of the coin is blank, but Paul's has writing on the back. The back of his coin reads "Association Francaise Des Artistes Pretidigitateurs". (see photo very bottom of page)

Additionally, he found an image of a plaque, which also has the 'Association....Prestigitateurs' on the bottom of the plaque and a bronze image of Robert Houdin in the center, with the exact same likeness as that of the coin. (see below)

If you happen to have any information regarding this coin and it's history, would you kindly contact Paul at paul@paulcourville.com
