Well, since you asked and I happen to sell all of my modern jewelry that I find, I would say that if all of it is indeed stamped silver.......
Ring $15 to $20.
Chain on the right $15 to $20.
The other chains $10 each.
Earrings $5.
These prices are based on me wanting it to sell otherwise you can ask for more and sit on it longer.
This is based on my 10 years of flea market experience. Prices are based on looking at a picture and may vary if I am holding it in my hand and personally inspect the pieces.
If you scrap it then expect about 40 cents a gram.
Not much else to say other than Nice finds!
Dave.
