'Pawn Stars' guest walks away disappointed as her postcard signed by Rolling Stones members is fakeThe guest had wanted $3,000 before she learned that it was not a genuine item. People come to "Pawn Stars" with hopes of making a quick buck for collectibles or vintage items that seem to be worth a fortune. Such was the case of a woman who thought she had a postcard signed by the founding members of The Rolling Stones. However, the guest did not know how that postcard had signatures of all five original members of the band. So getting the signatures of all five founding members on a postcard wasn’t exactly something that a lot of people could manage.
