How much money should I sell a iPhone 6s Plus?

It's unlocked minor scratches on top and bottom but not in the screen

Just give it to a friend.

$300. I would be very wary of buying a used phone.Ill say what's wrong and then you will lie to me

I just got $160 for a 6S Plus but it was in perfect condition, no scratches at all. So maybe $100-$125.

The going rate for the iPhone 6s plus is about $175. I always look on eBay to get a good idea of the market price for something.
