Thanks everyone for your input. I know now that I am not alone! It seems to get overwhelming at times to start putting all sorts of new sets together, loosing focus on one, concentrating on another. Most of my issues came from when I first started collecting, bought a bunch of random coins then realized that they were proabably not worth what I paid. So now I try to buy the right coin only once, which is pretty hard to do :)
And yeah JBuck, i'll be the ghost that haunts anyone trying to sell my collection once I hand it down etc.. :)
