hmm.. not many people would pay anything for the hexed mod, and battlepick isn't the greatest skin.
so you have 2 choices, basically you can either sell as is, without risking salvaging something other than the mod, or salvage the mod and sell it
in the mod baseline thread, it prices the mod at about 8-10k, but if you sold the pick, people would buy just for the mod, and therefore pay less because of the risk...
