10 year old speakers are bound to have some minor aesthetic flaws. If you can't easily see the cracks from 3 feet away, I don't think it's a big deal. Rate the speakers according to the Audiogon standard and price them accordingly.
As long as you are up front with the condition of the speakers, you should be able to get a fair price for them.
