 When the buyer is unable to evaluate an object, they consult with a knowledgeable expert who can evaluate it to determine its authenticity and potential value, and in the case of items needing repair, the cost of restoration or preparing the item for sale.Whoever is evaluating the object goes over the potential value with the customer, including the expert's opinion, if one is given, often interspersed with an interview in which he explains the basis of his decision to the viewer.A price tag graphic at the bottom corner of the screen provides the ever-changing dollar amount as the two haggle over the item's price.
