This sterling stamp dispenser by J. E. Caldwell of Philadelphia, PA is in good condition. This has a linear ding on the front as shown and three small pin point dings to the back with normal wear as expected for an item of this age. There are no monograms on this piece. The first coil (roll) stamps were issued on February 18, 1908 by the United States Postal service in response to requests from businesses. This piece is 1 1/2" tall, 1 1/4" wide and 1 5/8" deep and weighs 1.89 ounces or 53.6 grams. Although, the opening is only 5/8" by 1/2" and would not accommodate today's stamp size. It would need to be modified by an experienced silversmith which wouldn't be difficult to do. Stamped J.E. Caldwell (partial J), sterling and the silversmiths marks above and below 24 and P314.
