Strange thing at last Sudays coin show around here. The dealer I usualy buy 2x2's from had two different sizes of them. The difference is the thickness. In a pile of 100 one of the types was a good 1/3 thicker than the other pile. The dealer said actually he has found several different sizes in thicknesses that he deals with and many people don't like the thicker ones since they barely fit into those plastic sheets with the 20 spaces for them. Most dealers at coin shows use those sheets in 3 ring binders and if the people can't get the 2x2's out, they get irritated. I bought 100 of each but the guy now would sell the thinner ones for a half dollar less/100 than the thicker ones. Confusing since he said most people want the thinner ones.
