American Airlines Silver belt buckle. I've never seen one before but I had this put away in my stuff for at least 15 years. It is not marked sterling so I assume its silver plate. There are no worn marks in the silver on the buckle sides, front or reverse. It does have surface scratches as you can see. I suspect it has not been worn just kept in drawers for a long time. It measures 2 7/8" long and 2 1/8" tall.
