I have just bought a stack of these 5 NCV training school chips from Grosvenor Clubs (now Grosvenor Casinos), one of the largest casino operators in England. I'm keeping one for myself, and the rest are available for $5 each including shipping to the USA. Paypal, Cash or Paris/Ballys house chips (I'm staying there on my next visit to Vegas, so they are as good as cash!).

Both sides shown in the scan.
