The "Cajun Pawn Stars" (Wed., 9 p.m. ET on History) were offered a potentially valuable autograph book on Wednesday night's episode. It was full of signatures of 1950s' country music stars including June Carter, Roy Acuff and Chet Atkins. Tantalisingly, it also contained Hank Williams' autograph which, if authentic, would be extremely rare and therefore valuable. The Silver Dollar crew brought in an expert appraiser to assess the autograph and he pronounced it to be genuine.
