Unless Charles or the UK admins wish to comment on here (I don't see the point in bothering them in an email) to offer the reason why they are in roulette chips and not jetons which may help.........
Why don't we ask people on the board what they think is closest to how they should be classed (although I expect the odds to be stacked against me for a number of reasons all of which are obvious but no worries, it doesn't matter) and hope that they answer honestly. You know, get other people's opinions, something you may not be able to comprehend I know, but you can try. They may even want to explain their thought process.
Are they American style roulette chips (as they are ND and in different colours like AR chips) and should be on the guide as roulette chips with no explanation as it is obvious they are jetons. I think that covers all the things you've said to justify where they are on the guide.
Or........ Are they French style jetons that should be under jetons with a note saying that they were used on the roulette tables (French or hybrid).
It's probably pointless as only 1 person so far has offered an opinion but it'll keep them (and you) the centre of attention.
I doubt anybody really cares any more (if they ever did) and doubt it will have any effect at all but it's worth a try.
Hopefully, it'll mean you can say something different instead of just repeating yourself and also, nobody has to listen to me any more.
You can start the thread and I'll try to keep away so it'll all yours. You can even say it is your idea.
Just try to stop mentioning and showing the table that says they are roulette, jetons and have a hot stamp.
Go on, enjoy yourself.
