Marie Zimmermann uses a M over Z inside of a circle that looks like a y. If the "Y" is reaching all the way to the inside edges of the circle. It’s probably a Zimmermann and could be worth $20,000-$$50,000.

Italy & Y in a Circle by: Anonymous
I have a sliver necklace stamped 925 Italy & a "Y" in a circle opposite the sliver stamp. I can't find any info on the circled Y.
