Still very new to the chipping world, but I have herd it many times that Paulsons will last you a life time!! But recently I basically gave away some 98 CDIs that elwere total bike tires, how is that possible in the home market? Easy the chips aren't very dense, they wear pretty quickly! Also seen several times where people use mint chips for shuffle stacks and within a month or 2 the square sharp edges are rounded off. And let's not even go there on flea bites on THC chips! I have yet to witness any of this on CPC chips, I'm sure they are out there but I haven't come across any yet!
I'd still pick well used CPC chips over well used Paulsons in a heartbeat. They hold up very well and become buttery.
I bought some random barrels of old chips recently, and it included about 10 red square-in-circle or
CSQ mold chips (maybe made by ASM, before
CPC took those molds over) that were worn to bicycle tires and also had fleabites. I had never seen chips in that mold or other ASM/
CPC molds in such worn condition before*.
But maybe a reason for that is just because Paulsons are the predominant chip used in casino and poker club settings where the chips get abused/worn down the most. [like at poker tables with metal dealer trays, where the dealers have to 'tap' (bang) any tip on the tray before dropping it in the - the Cleveland Horseshoe $1 chips were flea bitten to pieces likely because of that].
Just a guess, but any chips (Paulsons, ASM,
CPC) that are worn to bike tires were probably used in a poker club that ran games several times a week to daily. So maybe these CDIs were used in that setting, (or were a shuffle stack/rack for someone with OCD about shuffling).
Maybe
CPC chips are more resistant to flea bites, I don't know about that one.
[EDIT - I posted pics of the 10 well-used
CSQ chips I had later in the thread here:
