Appraisals or bills of sale have little bearing on the price you’ll get when selling. Generally, you won’t get more than “scrap” value.
Take each item to several places that buy jewelry and get competing offers. Try pawnshops, especially when selling gold. Most jewelers do not buy used jewelry.
To get more money, sell to an individual (such as to a friend or relative) through a private sale—you might get as much as 50% of retail.
Sell through eBay. This is reasonably safe if done carefully and if you use a third party, such as PayPal, to handle the financial transaction.
Note: Protect valuable jewelry from being stolen before you can sell it by storing it in a hard-to-find place, such as a hollowed-out book. Never use a jewelry box on your dresser. That should be reserved for costume jewelry only—if anything is stolen, it will probably be that box.
