Not to get too far off-topic, I liquidated a HOF type set I was working on last year in favor of the Nifty Fifty. Probably 200 cards in total, all gone. It was tough to do, but it's been a great way for me to maintain focus on a handful of special cards instead of picking up every nice-looking HOFer I could find. I can definitely attest to the fact that when I'm limiting my core collection to 50 cards, I'm very careful about what I buy and how much I'll pay, because if I buy a card I have to sell another to create space for it.
I will admit that certain issues - like Gold Medal Foods and R311s - didn't get liquidated. In those cases I just pretend I don't have the cards anymore. And when I buy new ones, I pretend I didn't.
