I just (well 2 weeks ago) sold an 8GB for a little over $200, but I don't know how the prices are now with the new release.
 
Why not just go on eBay and search the completed listings? You probably won't get much more than $200 for it.
 
Buying Tips and Advice
https://forums.macrumors.com/forums/54/

Pricing advice threads now permitted

The Buying Tips and Advice forum is used to ask for help with purchase decisions and to discuss retail prices and deals. Now it can be used for an additional purpose: to ask for pricing advice, if you use the new Price Advice thread prefix.

If you use the thread prefix you can ask for advice on setting a price to sell an item, ask what your items are worth, or ask how much to expect to pay for an item. Other users can post to let you know what they think.

This is not an invitation to treat the Buying Tips and Advice forum like the Marketplace forum. If you fail to use the Price Advice prefix or otherwise indicate that you are interested only in getting advice on the price or value of an item you want to buy or sell, not in buying or selling at MacRumors, then the moderators may post a reminder in your thread. If you see offers to buy/sell/trade in your thread, report the posts so the moderators can remove them and keep your thread open.
