Why not? If you are not playing it and don't think you will miss it then sell it. Sometimes a pin has to go to make room for something else. Doesn't matter if one pin is harder to find or ranked higher by the masses. If you have had your time with it and it makes sense to trade it for something else, do it. LOTR is not that hard to find and neither will be Iron Maiden. Both should be easy to buy/sell since they are great games.
