Lines like Dcu classics and MU display much better loose. To state the obvious never open vintage moc unless the card has extensive water damage,erosion or otherwise looks undisplayable.
Or you don't care about displaying your collection.
If a card is beat to hell you will most likely get more $$ selling loose. Because a mint loose figure sounds better than a rough/poor condition carded example. the rare carded megos and kenner Star wars would be the exception to that rule. Because of the run of loose figures.
