Good day all. I am new to the forum and have only been detecting for a few months. I was recently vacationing in a very uninhabited portion of DownEast Maine. Miles of pristine beaches with no recent human activity except for lobstering in the water. Near an old stone quarry on the coast I discovered what seems to be an old slide buckle type item. It also seems to have been plated in gold. It is EXTREMELY thin which makes me think it couldn?t be a slide buckle. Would bend way to easily. The find was made on the beach so this item has been exposed to seawater. Any help on identifying this item would be greatly appreciated. I am attaching photos with size for reference. I apologize if I screw this up being my first time!!!!
