I have all of them.
The jetons are drestroyed when they are retired from the tables. Only a few survive ( mainly those that were buyed before that, by face value)
What As I can see is that obsolete european jetons has not the right valuation.
What would be the right valuation of a jeton, if for instance there are no more than 20 examplars of it? or 10? or..
As obsolete jetons and plaques (mainly) are scarce or rare,there are no more than a few strong collectors- I think
