Vintage/Antique Large Indian chief button

Up for auction is a nice old large button of an Indian chiefs head. The button looks to be hand made. The back plate is one piece I believe steel and the Indian head is attached by the shank through a hole in the back plate and is a little loose.
The Indian head looks to be made of brass with 9 black diamond cut beads on the head dress.
The button is 1 1/2 inches in diameter.
If you have any questions contact me before placing a bid.
Thanks
