Doctors who may want to spend their retirement making some extra cash might consider selling their treasures on Ebay. A recent article in Bottomline has rated the value of items on Ebay, such as books, electronics, art, and animal collectibles. If you are considering selling books, classic first editions of children's books are fetching high prices. A first edition Winnie the Pooh by A.A. Milne sold recently for $500. Other big sellers include early editions of Alcholohics Anonymous's The Big Book and oversized books with large prints of flowers or birds. However, you may not get much for your old mass market bestsellers or paperbacks.

As for electronics, used iPods in working order are fetching 50% of their original price, while iPods still in their packaging are receiving 80% to 90% of their retail value. Folk art from unknown artists, particularly works prior to 1900, has the potential to fetch thousands of dollars. What is not hot are works from today's unknown artists, which sell for $30 or less. Animal collectibles that are dolphin-related are the top sellers followed by dogs, elephants, cats, and birds. Interestingly, frog-related items are the least valuable, averaging less than 50% of the value of dolphin items.
