Can I sell a customized iPhone?

I want to change the back of my iPhone to a pink custom back. Same with the front. Will it sell more or less? Tried googling this and can't seem to find an answer anywhere. Any help would be great, thanks!

Not really sure how much you can get for it but changing it to pink would prolly only limit the people your selling it to. I dunno any guy that would want a pink phone unless its for his girlfriend or daughter. Lol but long as phone is in good condition and what style you should be good
