Looking up completed listings on ebay, one sold for as little as $5. Othes sold at $50 when the person listed missing capacitors. How was the chip damaged? I would have thought it difficult to damage a LGA chip via broken pins, but maybe something else went wrong.
Either way, if you list it, make sure you list that it is damaged / broken and list it in the for for parts / not working category and detail how it's broken.
