Riverdale has one or more collectibles dealers. A collectible, also called a collector's item, is an object which can value in the eyes of a collector, for its intrinsic beauty, interesting facets, history and so on. These can be items such as such as books, watches, jewelry, coins, stamps, automobiles and so on. The collectible commerce is based on people who like collecting such objects, and is not based on regular market needs. A dealer has to be enthusiastic about finding such objects among real estate auctions, rummage sales, and so on. He has to create and maintain an inventory of the items he has available for sale, and also the history and provenance of the item. He also can help locate hard-to-find collectibles for clients, and help negotiate both buying and selling of such objects. This can be an exciting, rewarding and educative profession. A dealer in Riverdale can specialize in certain collectible items, such as coins or automobiles. The prices depend on the quality, age and other considerations.
