Just sell them.
I'm not saying that it is missing a disc but even though .6oz (the exact weight of a game disc) doesn't sound like a lot it is actually quite a large variance for two copies of the exact same game.
I have a fairly expensive scale that is supposed to be accurate to .01 of an oz.
So it is concerning to me when one copy of a game is 3.4oz and the other is 4.0oz.
I have never run into this before and I have sold a lot of games. The only time that weight has varied that much for the same sealed copy of a game is when retailer specific games are involved (i.e. a different sku) and one retailer has an extra item package in or if the first print contains something extra like the skyrim map.
