I collected from Beta to Visions. When I sold my cards (other than the early sets which I had 4 cards of including rares) I sold them by the weight. The only ones I kept were my original Mox set that I had autographed by the artist. These are in a frame on my wall.
I figured I could keep 450 lbs of cards or sell them and
buy a new car. The car won out. (in hindsight, I should have been more selective in selling them off)
