I've always been a poker player who appreciates nice chips. I don't think I'm a full on chipper because for the most part, I'm not big on where the chips are from or the history behind the chips (some what but not high on my list at least).
I care about having a complete set that plays well, looks good, and feels nice. If I was no longer playing poker, I wouldn't be as interested in or keep so many sets.
That said, I still appreciate and will avoid any permanent change on harder to find/more rare chips because I get how hard it is to complete a set sometimes. Some sets just require it though since there are some denoms that aren't available in quantity. Also when the chips need a shaped inlay to match with other sets, your options become much more limited so I understand the chip reassignment work done with some hot stamps.
