Sterling silver tray/wine coaster made by Tiffany&Co and presented as a prize in a 1929 Horse Show. Its a rimmed dish that could function in numerous ways. Fully hallmarked on the back with style numbers and the "m" stamp used on Tiffany silver manufactured between 1907 and 1947. There are some small dark spots on the front and one scratch on the back shown in the photos and the price reflects this but otherwise it is a charming memento of the 1920s. Measures 5 1/4" in diameter and is 3/8" high.
