Notes: Normally, if you don't need collectible quest items and want to get rid of them fast for some money, you trade 5 of the same type for a Superior Salvage Kit. But in this case - for the reason that you can trade seven Trade Contracts for Gemstones - you can get much more profit from this trade rather than from a Salvage Kit.
