Vintage Textured Gold-tone Button Clip Earrings

Vintage clip earrings made of metal. These are gold-tone metal. The back part of the clip mechanism has lost its gold-tone color. Rest of earring has lots of gold-tone color. I don’t see any color loss on the round part of the earring. These have a little weight to them. They are better quality earrings. Unknown brand or maker. Approx 1 1/8” diameter.
