pawning

Scenario: A handsome fellow takes an item still listed by retailers at $1,000 into a pawn shop with the need for a loan of $500. He explains to an employee that the money is needed for an urgent unexpected expense. The employee of the establishment looks up the item, according to specifications, to see "what it's worth". He then turns to the man and tells him "aaaaahh well I definately cant give that much for it, $50 is really all we could do.[ FYI: Item is a military night vision(real deal night vision), GPS, WI-FI enabled rifle scope originally purchased for aprx.$1,200.] The man confused asks the employee(apparently deaf in the ear he was spoken into)"How do you come to that amount for this!?, seems a bit umm.... rediculous.". The man then repeats his reason and for a $500 loan(This time a bit more assurtive as to accomodate for possible hearing imparement). The employee turn his computer screen to the man and shows that his assessment of the collateral's worth was made using a site called Ebay.com. He scrolls down to the very bottom past all of the $1000, $800 and $750 range listings to rest his screen on a listing for $200 from a seller that for whatever reason didnt care what it's actual value was. After a ten minute round of unwanted haggelling with the employee as well as a supervisor on duty and resisting the urge to render a living man into a non-living man, he finally takes $130 for his collateral in protest of their appraisal practices.

In regard to this scenario, are there any statutes, codes etc, that can be used to make an effective claim and have the property returned or get a more reasonable amount of money? Maybe a way to hold them to a more reasonable method of appraisal and re-negotiate the loan ........ that handsome fellow feels extorted and ripped-off, they use EBAY!!!!!!!!
