IPhone 5 screen replacement cost or how much I can sell my broken iPhone 5? Color black?

My iphone 5 screen broken, digitizer and lcd both not working. How much I can sell it? If replace the screen how much it cost?

Saw some people sell old phone on craigslist, you can try it. I think you can ask repair store about how much, they can replace new screen and sell it as second hand. Maybe eBay?

Well if it doesn't even work, why would someone buy it.
