value. The pawnbroker assumes the risk that an item might have been stolen. However, laws in many jurisdictions protect both the community and broker from unknowingly handling stolen goods. These laws often require that the pawnbroker establish positive identification of the seller through photo identification (such as a driver's license or government-issued identity document), as well as a holding period placed on an item purchased by a pawnbroker (to allow time for local law enforcement authorities to track stolen items). In some jurisdictions, pawnshops must give a list of all newly pawned items and any associated serial number to police, so the police can determine if any of the items have been reported stolen. Many police departments advise burglary or robbery victims to visit local pawnshops to see if they can locate stolen items. Some pawnshops set up their own screening criteria to avoid buying stolen property. The pawnbroker assesses an item for its condition and marketability by testing the item and examining it for flaws, scratches or other damage. Another aspect that affects marketability is the supply and demand for the item in the community or region. To assess value of different items, pawnbrokers use guidebooks ("blue books"), catalogs, Internet search engines, and their own experience. Some pawnbrokers are trained in the identification of gems, or employ a specialist to assess jewelry. One of the risks of accepting secondhand goods is that the item may be counterfeit. The customer can either sell the item outright if (as in most cases) the pawnbroker is also a licensed secondhand dealer, or offer the item as collateral on a loan. Most pawnshops are willing to negotiate the amount of the loan with the client. Determining amount of loan To determine the amount of the loan, the pawnshop owner needs to take into account several factors. A key factor is the predicted resale value of the item. This is often thought of in terms of a range, with the low point being the wholesale value of the used good, in the case that the pawnshop is unable to sell it to pawnshop customers, and they decide to sell it to a wholesale merchant of used goods. The higher point in the range is the retail sale price in the pawnshop. In determining the amount of the loan, the pawnshop owner also assesses the likelihood that the customer will pay the interest for several
