Does this situation falls under the Fraud,Misrepresentation Good Faith and Fair Dealing? My husband sold a valuable piece of my silver to a pawn shop.

I had a Gorham Sterling 14inch Tray and my husband sold it to a pawn shop without my permmission for $100.00 ,I found out and insisted he get it back ,he said the pawn shop gave no reciept and did not ask him for I.D. or record any thing of the transactions. Pawn shops by law are required to record all transactions of the business,buying ,selling and pawning items that come in thier business are they not?Since the pawn shop is the expert and has more knowledge than the common person off the street it was thier duty to value the item and then make a fair deal on the price ! ( $100.00 ) for a antique Gorham Silver Tray ($1500-$2000) is not fair dealing practices,not to mention they did not follow the laws governing pawn shops in our state against receiving a possible stolen item. Would I have a valid case ?
