PAWNATHON CANADA (History, 9 p.m. ET/PT) Welcome to the Canadian version of Antiques Roadshow. Whereas PBS’s Roadshow is a genteel affair that invites people to bring in items for proper appraisal, this show is filmed over a four-day swap meet in Toronto and involves hundreds of people bringing in objects ranging from antiques to bizarre memorabilia. Each item is assessed by pawn masters Howard Green, John Kantymir, Douglas Stocks, Alison Ross and Mark Bradac, who affix a dollar value to each item and then scrap amongst themselves to see who takes it home. And it’s not a pretty business. In tonight’s opener, Mark haggles with a customer over a harp, Alison buys a banjo vase and John questions the authenticity of photos taken of John F. Kennedy’s 1963 trip to Berlin.
