I've never seen anything higher than the £100 from the first set but when I saw the photo it struck me that it had the same look. Just a hunch.
It's not from the film, just a photo that somebody found and thought it was the £1000s that are in the film (which you can't see and wouldn't know if you didn't know about them) but I'm sure it isn't.
Only ones used in Dr No are the £1 jeton (2 are seen), £10, £50, £100, £500 and £1000 plaques.
Considering the casino sent £35,000 worth there isn't much value on the table and looks like nothing on the other 2.
