I have a few UK and Nevada chips on EBay - including the Limited Edition Birthday chip from the Rendezvous Casino in Brighton. First LE that I have seen in the UK that has a serial number (and we don't have many anyway!)

Nevada chips are below face - $1, $5 and some $2, $3 and $2.50s

Thanks for looking

Jason
