what would a used 8KHA+ be worth

I just upgraded my pc and was thinking of getting rid of this and the 1800 xp chip I have , would would be a good asking price, has been overclocked but working when pulled have book, cd driver's , ETC.

I just bought two refurbed 8kha+ motherboards for $25.00 each. Although this isn't the place, and I do not yet have the number of posts required to get into trading, I would be willing to give you $20.00 for the chip as long as you know it works.
