Plz help, what is this worth? Dropped tonight when farming for gold, seems like it should go for at least 15,000,000 on GAH? or More? Less? What are your thoughts?

I never seem to have anything drop this good for me, and the most I have sold anything on the GAH is like 750K.

Thanks for the help in advance.
