Well, it seems the £5 chip in the scan above isn't as new as I thought, and so it appears likely that both £5 chips are in play and the casino has kept the racks of different tables 'clean' with some tables using one version, and some tables the other. I picked up this one on 3 card poker, but my last visit (and the other version of the chip) was on teh Caribbean Stud poker table! Guess I need to go back again and verify all this...it's a hard life, but someone has to do it
