Samurai swords brought back from Japan in 1898 by the owner's grandfather; late 19th-century journals from a country store near Grand Forks; and a mid-19th-century heirloom Bennington pottery lion.

ANTIQUES ROADSHOW arrives in Bismarck, North Dakota, where host Mark L. Walberg and appraiser Suzanne Perrault dig up a wealth of information about the University of North Dakota's School of Mines pottery program and how valuable these 20th-century pieces have become. Appraisers at the Bismarck Civic Center unearth a rich vein of objects, including a valuable set of samurai swords brought back from Japan in 1898 by the owner's grandfather, a member of the North Dakota Volunteers who fought in the Spanish-American War; late 19th-century journals from a country store near Grand Forks, documenting life in the early stages of North Dakota statehood; and a mid-19th-century heirloom Bennington pottery lion valued at $4,000 to $8,000.
