63 Pa. Stat. § 281-16
Notice of a pawn ticket which has been lost, destroyed or stolen shall be furnished to the pawnbroker by the pledger in person or by registered mail. The receipt of notice by registered mail of a lost, destroyed or stolen ticket or the issuance of a stop ticket by the pawnbroker after personal notice by the pledger of a lost, destroyed or stolen ticket shall be treated by the pawnbroker as a stop against the loan. The pawnbroker shall require the alleged pledger to furnish an affidavit or written statement as to the loss, destruction or theft of the pawn ticket. The pawnbroker, upon receipt of such affidavit or written statement, shall permit the pledger to redeem the loan or shall furnish the pledger with a duplicate pawn ticket, and the pawnbroker shall not be liable for any pledge released on such affidavit or written statement, unless previous written notice by registered mail of an adverse claim was received by the pawnbroker or a stop ticket was issued by the pawnbroker.
Whenever a pawn ticket is presented to a pawnbroker, which pawn ticket has previously been reported to such pawnbroker as lost or stolen, the pawnbroker may seize and retain such ticket on behalf of the rightful owner without incurring any liability whatsoever to the person presenting such pawn ticket.
Whenever any property is offered to a pawnbroker as a pledge which is stolen property or which the pawnbroker has reason to believe is stolen property, he may seize such property without incurring any liability whatsoever, either civil or criminal. Upon such seizure of property, a seizure receipt therefor shall be issued by the pawnbroker to the person from whom the property was seized. Such property and a copy of the seizure receipt shall be delivered immediately by the pawnbroker to the police authorities.
