When I was in the NAVY and on deployments over seas I wore a plain gold band ring with my name ingraved in it.I also had a heavy link silver braclet.It was always my thought to use it as barter if need be.I also wore a LARGE silver greenman ring that was a trademark of mine on ship.If it was seen on another person locally it would have meant foul play was afoot....
