Thanks... One of the three "white" I mention was the largest BG plaque I ever had; and their largest production back then was 151 x 105 mm (very close to 6" x 4").

I'm searching for the size of both £10,000 and £100,000 Playboy Club - London, along with information of some Portsmouth BG plastic laminates...

...and though this information below is known of the Gold £100k, my mention of only 10 of the plastic might have been made which was based on other high denoms by BG, might be way off and totally eliminates them being samples... from what I have read so far (table action)... which really doesn't matter to me since I would like to find pics for ChipGuide.
