Note: Weapon Fragments, Alloys, and Elerium are used to manufacture most items in the game. This is why their resale value is so low and why obtaining a precise number required for each project is so difficult - due to variances in the number of engineers, workshops, etc. Unless you are seriously strapped for cash, try selling something else instead.
