The best way for you to appraise the value of antiques is to take your items to a professional appraisor. he will have the best idea of an items real worth.
AN AUCTIONEER will probably be able to help. He might know the price that such items are selling for at the momemt, or he might suggest the name of a specialist who might know more about antique...
