Antiques Roadshow host Mark L. Walberg travels to a historic Civil War battle site. He’s joined by appraiser Rafael Eledge, who displays some valuable Confederate belt buckles and instructs collectors how to avoid falling for a fake.

At the Kentucky International Convention Center, there’s authentic excitement over such original finds as a late 18th-century heirloom Kentucky sugar chest; an 1860 rococo revival table whose top sports a painting of Mt. Vernon; and a pair of boxing gloves signed twice by Louisville native son and World Heavyweight Champion Muhammad Ali — once as Cassius Clay, in 1963, and again as Muhammad Ali 40 years later — valued at $2,000 to $3,000.
