How much can I sell my iphone for? - 2

I have a 32gb Black iPhone 4S on the Rogers network. It does have a couple problems however. The ear piece speaker is quiet, and the regular speaker distorts sound on higher volume levels. But it is a fully functioning phone that I intend to sell completely honestly. It is in 6.5-7/10 condition, just because of a few dings and scratches.neither the front or back glass is broken.

how much would you think would be a fair price to sell it?
