Antiques Roadshow 8 p.m., Channel 2

PBS’s “Antiques Roadshow” has been appraising stuff since “Pawn Stars” was just a glimmer in the History Channel’s eye. Last summer, “Antiques Roadshow” filmed three episodes at the Boston Convention Center. The first one premieres Monday night, and it features Mayor Thomas M. Menino, who brought in a 1948 oil painting for appraisal. Also under inspection: a Paul Revere print and a 1915 Red Sox World Series baseball signed by the team. Beforehand, at 7:30, PBS is featuring “Behind the Scenes at Antiques Roadshow,” a special about the filming of the Boston episodes, hosted by Jared Bowen. Pictured: A Boston guest and her Norman Rockwell collection.

Larry Hagman died after filming five episodes of the second season of this reboot, which returns Tuesday night. J.R. will also die this season; no long trip to the farm or to Europe for him. Will it be another “Who Shot J.R.?” situation? According to executive producer Cynthia Cidre, J.R. will not die of natural causes. Whether a gun is involved is still a mystery.
