Hi, I’m estatic I found this forum, the information and education here is unparalleled. I think I’ve been reading old threads for 3 days now, lol. I have my doubts on this ring,and ask very much a novice, with a desire to learn as much as possible. I purchased this a little while back looking for a period piece that I could wear everyday. Anyway, just judging by prior knowledge gained here, I think it’s NOT authentic. The inside reads, "U-593 18 August 1943 KM," also, "800." I’m pretty sure the date is when uboat 593 went down? KM, standing for, "Kriegsmarine," and, "800," meaning silver. Originally, I thought it one of a kind until I googled and seen this ring previously being sold quite often online. As well as chatted with another owner of the same piece. Is it possible the ring is a kind of memorial of the fallen or just a straight junk piece? Thanks.
