How much would you buy an iPhone 4 for? - 1

It is in very good condition besides a few stratchs along the edges from an otterbox case being on it. It is a black iphone 4. How much would you pay for it?

I only got $50 for one I just traded which was in perfect condition. I wouldn't pay more than that.

Like $5 considering its outdated. Or at least soon to be once Apple stops supporting it.

I wouldn't buy one, so $0.
