Does this woman on Pawn Stars really have a guitar signed by the Beatles?

I love the show Pawn Stars, but am always amazed that someone would take something that could be nearly priceless to the shop to sell it! Wouldn't you take it to an auction, a collector, a museum? Well, here we go again, someone with an incredible item that walks into the pawn shop. This time she has a guitar signed by all 4 Beatles in 1964...or does she? She insists insists the acoustic guitar was signed by all four of The Beatles in 1964. Here is the scene and how it all plays out, from the show entitled "Ticket to Pawn."
