The actual value of an item can be determined by trusted marketplaces that can provide a professional opinion on the item's value. Apart from searching websites for the reliable selling value of an item, the experts from popular auction houses or marketplaces can calculate an item's value. Prices and value guides, which are authored opinions, are available online.
A seller should look for the manufacturer marks and determined the size and condition of the item prior to listing it for sale, advises collectibles expert Barbara Crews on About.com. The seller should photograph the item before listing. Detailed information on the item may be gathered from collector's books available in libraries or at the local bookstore. One can search the auction area of any online marketplace, such as eBay, for details of similar items. Searching for the item?s price in online malls, such as Tias and Ruby Lane, could give an idea of the item?s value.
Online collectors clubs that deal in similar items may be helpful in determining the value of an item. The image of the item can be posted in collectors forums to get help regarding its value. The figures suggested through these methods could be averaged to provide an approximate value of the item, Crews suggests.
