One Penny might not seem so impressive these days, but there is real beauty in these old coins. The ring is sizeable, and has been hand painted to enhance its mystique. The coin is finished with a protective coating. The ring is 33mm across the top, 30mm from top to bottom and ring size M, or 16.3mm. This ring can't be resized but I could make one to your specifications. If you need help finding your size just email me and I will help you. Penny for your thoughts?
