~~~ you estimate in France/colonies... or even in all Europa...?

Years ago I knew of at least 14 collectors (4 male and 10 female in casino work) in Romania, alone, who were casual collectors. Some were even at work at sea; here in Florida.

I know that a large number of French numistmatis maintain metal casino jetons in their collections.

How many books you think there are in Europa, such as those by ELIE, Tores and REYNCKENS?
