Vintage Christian Dior Gold-Tone Circular Earrings Clip Ons

Vintage rare Christian Dior clip on earrings. They have some tarnish/ rust (not sure what to call it) on the back and inside the clips. You can't see it from the front. There is a sort of dull spot on the front top circle of one earring too. You can see all of these issues in the pics. Still very good condition for earrings that are at least 50 years old and still have the holder. This is a rare piece that I've only displayed in my collection. I've estimated the original price to be what they're worth now.
