Hello, I am new here and have been searching without any luck on where to go for jewelry marks information~ Thank you for your your help on where to go.
Also, down in the Garage Sale section, is a master list, that has been stickied to the top of that forum.
It may or may not have the info or reference for what you seek, just thought I'd mention it, and provide a link. It's a little old, too, from back in 2012 or so....
Good luck in your search for info....
