Gorham Sugar Sifter

This Gorham Sugar Sifter Spoon ladel is scalloped (almost shell like) with lines of sifting holes.  Top of handle is very simple and comes to a point at the top.  I am not sure if it is Sterling Silver or Gold Washed silver- although it has a goldish tint to it. On the back at the bottom of the handle just before the label it is marked "Patent 1861" and towards the top of the handle are the 3 Gorham Lion, Anchor and G markings- all are by themselves without any shape around them.  The Lion is facing the right and on all four legs. The spoon is slightly tarnished and the top of the handle may be bent a litle out of shape.
