You have a wonderful waste bowl or sugar bowl without the lid, not sure. Does it appear to have a lip for a lid, or some wear along the rim that would indicate a lid. If not then it could be a waste bowl. Never heard of Marlford Silver plate, looked a bit in a few books and at replacements, can you get a better shot of the hallmark, is it possible it is Medford? Based on appearance looks late victorian or real early 1900's. If in fact it is a sugar bowl orphaned from it lid, the value would be a few bucks at best, Waste bowl maybe a bit more. I will look a bit more for Marlford, but have a feeling it is Medford.
