I had all these cards in the 90's, 2 sets of Moxen, 2 Black Lotus (all unlimited), but sold a long time ago. We didn't know this was going to happen right?
Despite this there are lots of Reserved List cards that are gaining value, though I'm not really convinced the demand is there other than other speculators. However I have a got together a 1000 box full of Reserved List rares from the mid 90's.. just in case.
Hold on for a few years and then sell! Especially Alpha, Beta, AN, AQ and LE.
