But the origin of these tokens still seems to be a mystery, with suggestions of Readers Digest and slot machine token. For now no more info on their use, but based on the tokens offered for swap I would suggest to change the origin to Belgium as the dutch version (Dukaat) is only offered by a Belgian member and the French version (Ducat) is offered by 8 Belgian and 1 Luxemburg member.
(Even in Spain they think it is Belgian
)If anyone has any more info, please share. If no one objects, I'll already move them to Belgium.
