Well, that's weird. The photos are the right way up in my usual browser but not the one I have to use when I post, hmmm.

Found out that these were released in July 1974 with only 100 being made.

GPI also confirmed the date and amounts for the "Dr No" plaques and I was also sent a photo showing that the casino sent over £35,000 worth of plaques/jetons to the film company.
It looks like there were a couple of red £1 jetons seen in the clip too.
Also seen, £10, £50, £100, £500 and probably the £1000 too. All released in April 1961 although it could be made/delivered so not 100% sure which it is but as the casino opened in May 1961 I'm tempted to say delivered.
Loose ends that a couple of people may be interested in hence my posting the information here.
