I know a gold and silver broker in Memphis TN, named David Yawn. Call him at 901-767-6968, and he can probably help, even if its referrring you to one in your hometown if you are not in Memphis area. Vey reputable person, whom I have known for over 30 years.
Personally, because I am an old sentimental softy and like to hold on to all my things, regardless of whether it is jewelry. my answer is do not sell your gold, silver or jewelry. You will never get back what was put into it. Passing it along to future generations is the name of the game if the jewelry is in good condition. If it isn't you can have it made into something different and exciting to wear or give as a gift.
