I looked at the edge you circled, no nicks, but there are some black spots there as well. I'd like to keep the gold wash, but I want to get a mirror finish more, so I guess I can sacrifice the wash :-(

If I were to send it off to be cleaned and restored, how much would it set me back? I don't really trust myself to do the work with it being my first time. Who would you recommend for the work?
