ANTIQUES ROADSHOW packed a trunk full of additional treasures from the eight cities that made up its Season 18 tour. ROADSHOW's bigger-than-ever 2014 season includes a second hour of never-before-seen appraisals, such as a collection of 1898 Mardi Gras invitations; Julia Child's copper pans, ca. 1960, that Child used on her TV show; and a German violin with a Sartory bow that is appraised for $25,000 to $27,000, with $20,000 of the value in the bow alone.
