I have this gold medallian with a small hook on the top of it and am not sure what it is or value. The front of the coin shows a man with his sleeves rolled up and sitting on a fence. The man appears to have a hat on,but it could be longer hair as well. The fence posts are capped with triangle caps as well. The back side of the piece shows nothing. There is no wording or lettering on the piece. The piece weighs 4.8 ounces. If you can help me with this, I would appreciate it greatly.
