Fans of may be in for a shock after the show's former host, Mark L. Walberg, admitted that, despite 13 years at the helm of the PBS show, he still "knows only a tiny bit more about antiques" than when he first started. Writing for the Huffington Post, Walberg, who is currently the host of Temptation Island on Netflix and Peacock, admitted "I will never be an expert on antiques. I will never be able to tell you if Ben Franklin once sat in that chair, or if it's from Ikea circa last Tuesday.

"But thanks to the people I meet on the road, I am beginning to learn what is truly valuable." But that hasn't stopped eager fans from putting him on the spot in the most unexpected places. "People I meet don't say hello. They don't introduce themselves. They simply push up their shirtsleeves and announce, 'My grandfather gave me this watch. What's it worth?'" he shared. And as if that wasn't awkward enough, some even mistake him for The Bachelor host, Chris Harrison. "Sorry, that's not me," he joked.

Despite his years on the beloved PBS show, Walberg acknowledged the vast expertise of the Roadshow appraisers. "Many of the appraisers we feature on Roadshow are third-generation experts.

The knowledge they've amassed can't be learned in one lifetime. They are amazing. Kooky, but amazing." He admitted that while the experts have tried to teach him about antiques, what he has truly learned is about value.

"The key factors that dictate value in the antiques and collectibles market are Authenticity, Rarity, Condition, and Provenance."

Rather than focusing on the objects themselves, Walberg's experience on the show has been about the people behind them. "My Roadshow experience is filled with priceless personalities, not Rembrandts or Civil War muskets.

"Although muskets are awesome. What I've learned is the four things that make antiques valuable hold true for people too."

One moment that stuck with Walberg involved an art glass appraisal with his friend Kathleen Bailey.

"In walks a guy with a beautiful perfume bottle with the Lalique mark on the bottom. Kathy asked me what I thought. It's her little game with me. She asks me questions like, 'Is it old or new? What country is it from?'

"She's kind and gently asks me the same way you would quiz a kindergartener that's learning to read. That's about where I am in my study of antiques. Kindergarten."

Despite his self-professed lack of expertise, Walberg was able to spot a fake.

"When I picked up the bottle and looked at it, I just knew it was a fake. And I was right. Even though it had the Lalique mark on the bottom, you could just sense that it was a reproduction.

"Maybe I shouldn't have been so excited to tell the guy his bottle was a fake. He wasn't nearly as happy as I was with this revelation."
