Hold on a minute.
This is interesting. Ive had no time to post but I bought the rack from a closed Isle of Wight casino last week, from the liquidators, and I was asked if I wanted the Kingsway £1 and £5 rack that came out of the same vault.
Very strange. I have some info on the IOW when I dig it out to post, hopefully this week. Maybe they were linked in some way.

Before anyone gets too excited, 95% of the chips I bought were either broken or so worn they are flat
There are only maybe 60 vgc chips (8 denoms) out of 7,500 chips. There are a further few hundred just about saleable.

Another thing. When I opened the 'archive boxes' which I guess these have been stored in for ages, the smell was indescribable
