I've always had a "soft spot" for the Connoisseur as I worked there for a few years after the Victoria after being "headhunted."
Again, I don't want to overload the post so will only show the 2 top denomination of each set.
The oval one is one of only 2 (of a set of 3) that I know of and they only exist as the Head of Security took them before they closed down. He's not the sort to do so without permission incidentally. I just wish he'd saved more.

The next one is also the top value of the 4 in the set and I only know of 3 sets. Pity he didn't manage to get hold of the £1,000,000 one but at least I know it has a good home (Doug, you lucky so and so).

All of the ones I am showing are on the guide already.
