The advantage of selling at auction 

Among the various options open to you (such as direct sale to an antiques dealer, small ads, sale-or-return stores or e-bay), a public auction remains the best solution for selling your objects at the best price in total security. This is because it ensures competitive bidding from various buyers potentially interested in your item, and guarantees a sale to the party making the highest bid. As the auctioneer is paid according to the money made from selling your objects, he/she is a genuine partner.
