Don't you know?
There are 100s of items only known notched, cancelled or as photos but nobody knows where they are or they would have rescued them by now.
All I said was that until they turn up, we can't know for sure that they existed although if photos in a catalogue are the best we can do then so be it. It will have to do. They probably did exist but were they used?
As to your eventually agreeing that they are jetons, great but you still say that they should be under roulette chips which doesn't seem logical to me at all. The clue is in the section title, chips. Maybe the guide could create a roulette jeton section but until then, they should be under jetons. Jetons are jetons regardless of what game they were used for, yes?
I thought it made it clear why I was asking for clarification as to what you classed them as in the context of the posts but obviously not.
There are many other examples of things that could have their own section (as mentioned already) but until the guide decides to add them, they'll just have to stay where they are.
Hopefully that makes sense to you now.
