If it was bare wire (not tinned) and the strands have punked out from green crud...try lopping a yard off the end, and repeating that 2-3 times if necessary, to see if the crud really worked in. If so, the scrap yard. If not--it is still good cable for other uses.
Heck, even if it is only so-so, it might still make a decent "when all else fails" marine-length jumper cable to charge the boat tied up alongside you.(G)
