Q: I have a Roseville floor vase that is my treasure. It was given to my great aunt and uncle for their 25th wedding anniversary by my mother and cousins. It’s marked “Roseville, U.S.A., 129-18” on the bottom. Can you give me some information on its age and value?

A: Roseville Pottery Co. began operating in Roseville, Ohio, in 1890 and opened another plant in Zanesville, Ohio, in 1898. The company went out of business in 1954. Your vase is in Roseville’s Freesia pattern, which was introduced in 1945. Freesia was made in Delft Blue, Tangerine (brownish orange), and Tropical Green. The numbers on the bottom are the shape number, 129, and the size, 18 inches. Freesia was made in at least 47 different shapes. Value of your vase: $800-$1,000.
