A three-episode stint in Seattle begins. Items appraised include a 17th-century Japanese tea urn, an acetate of a recording by Seattle native Jimi Hendrix, an 1819 book its owner found in a dumpster and a baseball autographed by the 1951 New York Yankees. However, a non-Yankee also signed it and that normally decreases value “dramatically,” says appraiser Simeon Lipman. But the non-Yankee was Marilyn Monroe, who, says Lipman, “is the exception to the rule.” Also: host Dan Elias visits architect Frank Gehry's Experience Music Project museum.
