My VZW unlocked 64GB iPhone 5 is in perfect condition; no scratches whatsoever. Box included etc. I used to see these going for $550-$600 on eBay when the 5s was released... now they're going for $400-$450? Doesn't seem right at all when the 16GB model is around worth $300+. What's fair for eBay sales at this point? I got no interest at $600 on Cl .
