Curtis Dowling and his team of investigators are out to expose the fakes! They are on a mission to help collectors of art and antiques discover if they're holding trash or treasure. In this special sneak peek, Dowling tries to determine whether one of the most sought-after sports collectibles of all time, a Honus Wagner T-206 baseball card, is real or fake. Often referred to as the "Holy Grail" of sports collecting, the card can sell for over $1 million, depending on its condition. But is this Wagner card real or fake? Dowling can't risk taking the card out of its protective case, so he must resort to high-tech measures to determine its authenticity.
