An 18th-century ivory carved crèche; a pair of “Barcelona” chairs; a circa 1900 Turkmenistan rug.

Host Mark L. Walberg meets appraiser Rafael Eledge aboard the USS Midway, the longest-serving U.S. Navy aircraft carrier of the 20th century, to discuss the evolution of a 19th-century sailor’s side arm: the cutlass. Highlights include an 18th-century ivory carved crèche that could be worth up to 30 times what the owner paid for it; a pair of mid-century modern “Barcelona” chairs: a line of chairs designed in 1929 by Ludwig Mies van der Rohe as thrones for the King and Queen of Spain; and a circa 1900 Turkmenistan rug, valued at $125,000 to $150,000.
