~~~ than the 100F round which is 43 mm and the 100F octagonal which is 44 mm; this lower denomination 50F rectangular is 46 x 30 mm and kind of unusual since lower denominations are followed by octagonals, ovals and rectangula shapes, traditionally and, leaves me to believe or at least ask... could this operation have been of a size where there were at least two sets of chips used at either diffent games or different locations while still being "CGT" or whatever the correct conclfiguration for the three letters are since we know at least two of the same denominations exists with the 20F and 100F...?

The Trouville mention exists only because a French casino Historian brought up the name as a possibility... We do not know (though there are other factors which do not amount to anything more than an assumption).
