Everyone finds their fun in their own way. Whether it's sets or chips or tokens or dice or cards, or players cards, photos, postcards, paper, shot glasses, slot glass, dishes, or room keys... or whatever. I don't see anyone ever being looked down upon, for whatever they might choose.

Joining the club, is for all and any casino history collectors.

On the other hand, single chips are the main interest of many, and why the Chip Guide exists. That doesn't ever mean that anyone else has ever been excluded. Sets are just a different interest.

That's my personal view. I like the history of gaming and casinos, and have a personal interest in probability and logic, which is not an item.
