These came from a retired Playboy/Curzon House/London Clubs exec (as have other old UK chips that I have offered).
He worked a short stint on QEII for London Clubs in the 70's. He says these would have been in use from when the ship sailed in 1969 and doesnt think the roulette tables were open for that many years.

The chips represent the two tables, the globe for one, and a ship for the other.
I have these 4 chips available and a duplicate of the purple and red. He has no more.

First time I have ever seen these. Email me if you have a serious offer for them.
