This is a simple ring carved from animal bone with a simple flat face. On the face is carved an anchor with a rope. On the side is carved U.S. and on the other side is "6 ME." and an 'H'. On one side of the band is "C F Me K", and on the opposite side is "S. E. Mc K." The ring is a small size measuring 5/8 of an inch in diameter. Research certainly a possibility.
