This was given to my late husband by his mother who collected coins. It has been locked away since then. I didn't remove the coin to show the other side as I don't want to damage the velvet box. It is in there really tight.

Never exposed to smoke, perfume, scent of any kind.  I strongly suggest Priority shipping to keep it insured.
