Pricing Help please? - Ring

I'm still sorta brand new to the game and got my first decent-ish Legion drop (I think?)

I've tried checking myself but can't really find anything concrete. I've seen some pretty similar at around 20c and one very similar up to 1 ex.
I've tried posting in other places and gotten answers from less than 5c if lucky and 20c-40c.

I was hoping someone might be able to help guide me a bit. Any ideas how much this is worth?
