Rare cast relief gold european coin coaster set

Rare set of what looks like a cast gold release, European coins, each in its own poster with cork backing. If you're looking for something elegant, unique and rare, this would be a great item. As I haven't taken this apart, I can't tell what the material is that each coin is made of. I've also done a lot of research and I can't find a set like this out there. Please see photo so you know exactly what you will be receiving.
