Until last year both these chips were extremely rare (about 5 - 10 of each know.

Then a car dealer in Southern England was GIVEN a box of chips by a neighbour for his home poker games. The neighbour was a training officer working for Pleasurama Casinos in the 1980's and used these chips on training schools (Pleasurama took over the Playboy Club in Manchester - rebranded as Cromfords - when Playboy & then Trident lost their licences to operate) In the box were over 250 of each value! The condition of these vary from v.poor to near mint - when the first few were listed on ebay they went for $250+ each, now the prices are down to $15 - $20 each. If you get a nice one I think they are priced at an OK rate... and I don't expect the value of the near mint ones to drop much further.

Hope this helps.
