A Victorian ornamental tree made of human hair. A rare Rolex watch preserved for decades in a safety deposit box. A binder full of Pokémon trading cards circa 1999.

Long before the experts of “Antiques Roadshow” identified these items as valuable, they could have been mistaken for plain old stuff. Maybe you own a few things like that, too. If you’ve ever wondered wistfully whether your junk is worth something, mark your calendar.

PBS’s popular series “Antiques Roadshow” is making a stop in Baltimore on June 18. The series, which is entering its 29th season, puts people and their antiques, heirlooms and yard sale finds in front of expert appraisers, auction house dealers and independent collectors. The show last visited Baltimore in 2007, according to a news release.

“We can’t predict the items that will make their way to ROADSHOW each Tour,” said executive producer Marsha Bemko in the release. “It’s that magic mix of serendipity and personal stories, with a little history thrown in, that makes each must-watch season and keeps fans craving more. I am thrilled for the show to visit Baltimore 17 years after our last visit and can’t wait to see what local treasures await!”
