Do you need to sell it now? Hold it until it really becomes an antique if you can. Otherwise you could get a nice sum at an auction or to a museum.
 
Apple II was mass produced. It may be worth something in a couple hundred years, but not in your lifetime.
 
I usually just go straight to Ebay. See what they are going for by BIDS not by what dealers are asking. If an item has no bids, ignore it unless its a new auction.

I just checked, Apple II E and Apple II Plus are going for $50 with drives.
1978 Apple II with monitor, controllers, drive, programs, and other upgrades up to almost $500

You can also check Completed Auctions on ebay to see the history of final prices on Apple II's.
