The reason why I decided to show it now is because in 1998, during the FUN Convention, an exhibitor from France had a single display case next to my display of four cases and in his display was only one chip; the round 20F pearl.

Prior to that I have had a few casino owners in France, search via families in the casino business in a few regions and nothing was founds and, afterwards, a couple examples of the 20F turned up in the Savoie... and, as far as I know nothing has been found explaining anyrhing.
