This is a vintage sugar spoon or sugar shell in the Her Majesty pattern made by Rogers 1847 Silver Company, USA now a part of International Silver. The pattern was made in the 1920-1930s and discontinued then.  

The silver plated spoon measures nearly 6 inches long. The perfect thing to accompany tea or coffee with an elegant classical and royally named pattern. 

The sugar spoon is in excellent used vintage condition with no plate loss and basically no signs of use.
