MAC-only Sierra games.
I got $90 for a sealed copy of one of the X-wing games; I knew it was a legit seal because it still had a coupon for a free offer of some kind on it.

That last Quest for Glory collection always seems to go for quite a bit as it was never re-released again after that print. I still kick myself in the ass for not keeping better tabs on that disc, and I remember throwing the box out thinking to myself, "this won't be worth anything." Jackass.
