went back to the same area that I found the sterling insignia,. My buddy found two more mercs. I found an old 1970s toy gun, "police 45"(it looks like a .32 ACP tho) and the 25.2gram 10K college ring. The owner passed away in 1963 at the age of 30. The ring was over 8 inches deep, rang 22-31 on the Nox, real jumpy.
