Are these metrics good?

are these metrics good? How much would you pay for this?

Metrics look OK, provided it's clean.
No idea what it's worth. Silly question, really.

It depends. Is this a known authority site (a competitor perhaps) or an expired domain up for registration?

If it's an expired domain it's probably too good to be true with that many referring domains i.e. Spammed.

Click on the back link profile and start clicking through some of them to see if they look like spam. There is a lot of info on this board to help you identify what that looks like.
