Host Mark L. Walberg is joined by appraiser Wes Cowan at the Iowa State Museum in Des Moines to look at its collection of highly prized sand bottles by 19th-century Iowa folk artist Andrew Clemens. Highlights include a late-Victorian 14-karat gold vest chain and fob; a pair of 1963 and 1966 Green Bay Packers signed footballs; and a rare collection of promotional movie memorabilia from Hollywood’s Golden Age, valued at $25,000 to $28,000.
