These were the main ones known although they were only ever seen notched before the "find" so I suspect they were samples (and not notched by the casino) due to the 1 x £25 that was withdrawn only being known notched. I think a 25p had been found previously but none of the other values. Many thanks to David Sarles for putting up the chip order forms, I still hope that he'll find the others too.
There looks like there was an issue with the inlays falling off even when they were at the casino as I have 100s in the proper black chip holders that UK cash desks use (with the metal bar to keep them in) that have 1 inlay (or both) missing. The inlays are stuck on with a foam sticky pad and they look unused, in the main. There are some that have expanded in the chip racks (normal clear plastic ones) so they are pretty much stuck in them and a couple where the "foam" has gone haywire and turned into a long "tube" which is quite amusing to see. They all needed a clean as they were covered in a dye-like dust and some even had the talc still on them.

There are just the rest of the 1961 plaques, 1978 plaques and the £500 metal LGK token left to put up on here so almost done. I hope that it has been of interest to some on here even though they are not American chips.
I also have the last roulette chips used (I assume) that were just the basic type so I've added them below to finish the chips off.

Thanks for looking and enjoy your weekend.
