Sell mobile display?

I bought a new phone, so I do not need my old one, it's a Huawei P8 Lite in black, and the glass is broken, but it's not older than 1 1/2 years. For how much money could I sell it should I have the glass repaired first? (The glass is not broken the pantper glass)

You can recycle that

Just look at the current offers on ebay for similar devices with defective or functioning display and looking for offers for replacement displays. The rest you can then calculate yourself.

Put it for 75 euro VB purely a repair is not worth it unless you fix it.
