question regarding Domain Names??

So i'm gonna take what you guys say with a grain of salt, and not make any hasty decisions regarding my questions, but i found myself in possession of a domain name that has a Domain Authority of 50, and a Page authority of 36. it only has 3 backlinks, 1 of the backlinks gives it a 283 root domains linking to it.....but even after the purchase i still have the domain authority, although maybe it takes longer than a week to update.

so my main question is what would be what kind of rank is this domain and is there anyway to figure out if its worth monetizing?


thanks in advance
