I have a small collection of chips in lucite. My basic rule is that the chip has to be much more valuable if it were not encased. Lucite is a very durable material. I am aware of attempts to melt and freeze the lucite to get at the chip. The basic problem is that the lucite clings very tenaciously to the chip and is a much more durable material than a clay chip. If you succeed in your efforts then I have a $100 Circus Circus Ringmaster chip that I'd like removed from bondage.
