Very Old Tin Concho Necklace Southwestern with Eagles

Vintage tin concho necklace. The conchos are very well made with repouseé designs and stamping. There are 4 round conchos, one rectangle and two eagles. I am sure that this was made from a belt at some time. It hooks at the back with two clips. It Measures 17 1/2" long. Round ones are 1 1/2" wide. The patina on this piece is amazing.
