[quote name='catacasa']Really depends on what you have that is also in the current 8th edition (as far as your 4th, revised, or unlimited cards would go.) And most of the alpha cards are fairly worthless since they can't be played in tournaments.

Without seeing what you actually have, it would be impossible to tell you if you could get 200-300 for it. It might be worth your time to just go through and pull all the rares out (and in very few exceptions, the uncommons such as Serra or Sengir, since they were remade as rares.) The commons usually aren't worth their weight in shipping, but that's up to you.[/quote]
Yeah, if your packing things like Birds of Paradise and Wrath of God, Dual Lands, then your gonna be raking inthe cash. Otherwise your box may just be worth next to nothing if it's just full of lands.
