I hear people say "I can get this or that out of these skins" but how do you know what you can get out of a skin?

The comment from GiantTree is correct, however I am answering here so the question can be closed and to give a more specific answer. Trade up Contracts give out skins based on what skins you put in. The output skin is both one grade higher than the inputs (Industrial will give you a Mil-Spec, Mil-Spec will give you Restricted, etc) and must be from one of the collections of the skins input.

For example, you could put in 5 Glock 18 Catacomb skins and 5 AK-47 Elite Build skins. Both of those skins are Industrial Grade skins, Catacombs is from the Chroma collection and Elite Build is from the Chroma 2 collection. Thus, you can get out of it any Mil-Spec skin from either Chroma or Chroma 2 (namely, Dual Berettas Urban Shock, Desert Eagle Naga, MAC-10 Malachite, Sawed-Off Serenity, AWP Worm God, MAG-7 Heat, CZ75-Auto Pole Position, UMP-45 Grand Prix).
