How much is my phone worth?

I have an IPhone six, the motherboard is broken, but the only thing wrong is that you can't call or text with it… It's basically a IPod. The phone repair store said that they could ship it off to get it fixed, and it would cost $120 to fix but there's only a 50/50 chance if it working. I bought it as a brand new phone from Verizon in September 2017. I'm just wondering how much I should sell it for? I just replaced the glass too. If you want to know anything else about it ask.

Sounds fairly worthless to me.

I wouldn't give $5 for something that I would have to send in to fix.

I also wouldn't give $120 to fix it.

I would say <$50.

As you said, there's a 50/50 chance of the repair shop to be able to fix it. That doesn't sound like it is worth much.
