How can I find the value of vintage jewelry online? I have about 100 pieces , mostly signed, that I am wanting to sell. I found pieces online by the makers that I have but I can not find my exact piece for comparison.

Names I have are Boucher, Monet, Whiting & Davis, Sarah Coventry, Japan, ect. to many to list them all
here's a couple examples.
