Q: My hammered aluminum tray is at least 70 years old. It’s marked “Hand Wrought Creation by Rodney Kent 423.” Does it have any value?

A: Rodney Kent is the name of a line of hand-wrought aluminum giftware that was developed for Krischer Metal Products Co. of Brooklyn, N.Y. Hammered aluminum giftware was popular from the 1930s through the 1950s. The Rodney Kent line was developed under the supervision of Stanley Gelford, who named the line after two streets near his office: Rodney and Kent. The line includes various serving pieces made of an alloy of aluminum and manganese. Most pieces are decorated with tulips. Some have ribbon and flower handles. Shapes were numbered from 400 to 499. The number on your tray indicates it is the 14-by-20-inch tray. Some pieces are marked “Rodney Kent Silver Co.,” although the pieces are made of aluminum, not silver. Some had paper labels or tags instead of a mark; others have no tag or mark at all. Prices today are much lower than they were in the 1950s. Your tray might sell for $25.
