Not in my eyes! Some collectors don't like to see gold coin pendants but that's okay, you can't please all of the people all of the time! Great looking piece!
Yes it's damaged as a coin but it's priceless in jewelry because of your wife. Enjoy it as a piece of jewelry.
Most likely damaged by the mount, but also looks clipped. I don't suppose there's any chance you weighed it before she mounted it, is there?
