Found in with my Dad’s jewelry. Don’t think it was his, might have been my grandfathers or one of my great uncles.
Not able to research thoroughly online. Great research opportunity for someone in the organization. While the stamping has worn considerably, one can still see a skull and crossbones adorning one side of the ring. I determined an elk resides on the other side. K of C easily identified on domed top.HB (?) stamped on inside of band. Size 9.
Took to jeweler who stated it is an older gold so if someone wanted to enlarge it, the newer gold would not match. Weighs 3/10ths of an ounce on my scale.
