I have a King Richard the Lionheart sword made by Marto that I got about 20 years ago. There are different versions of this sword all over, but none like the one I have. On mine there is writting on both sides of the blade. Side 1: RIChARD I Side 2: COEUR DE LION. I was wondering if anyone has any information about this sword as I cannot find anything about it and am considering selling it. Thank You.
