I can relate. I look at a lot of exhibits and just having the coins in slabs bugs me, I think it make the exhibit unattractive. It is even worse when they are from different TPG's. And even if they are from the same service, I want them to be in the same generation of holder. You want to really bug an OCD Rubic's cube person. Take a completed cube peel the stickers off ONE corner piece and rearrange them, then scramble the cube.
I don't know if I would call it OCD as much as I would call it an attention to detail. I don't get so hung up on them all being in one TPG but I can certainly see wanting all blast whites and no toners. I'm doing the same right now with a Walker short set.
It pains me when I cannot rotate and inspect coins that do not belong to me. Doubly so to spend any that have not been "checked".
I think that almost any collector of anything ( including coins) is OCD to an extent. If you can't walk past a coin on the parking lot payment without stopping and picking it up to see what it happens to be, you fit into that category. If all of your singles collection has to be the same color of tone, yes, etc. Everyone has it to a slight degree, just do not let it get pathological such as rearranging your neighbors potted plants because they are out of order, or segregating the apples in the supermarket so they are in order of redness or size. As long as its your own stuff and in the privacy of your own area, which you have already rearranged multiple times to be just right , no harm.IMO, Jim
It is a little corny by today's standards, but if you want a good laugh download/stream/rent "Good Time For Sergeants". You will not be disappointed.
I read once that Don Knotts was a drill instructor in the Marine Corps. No reason not to believe it except: " Don Knotts? A Marine DI?!! Yeah, right!!! "
Since you have multiple cubes take them apart and build new ones with all one color. Now you can spin them as much as you want and never feel frustrated.
I took up woodworking years ago to satisfy my compulsiveness. I can sand a piece of wood for hours on end and not drive anyone else nuts.
