Is Sheffield plate worth anything?

Yes, Sheffield plate may be worth something. Generally, the maker, age, style, type and condition of silver-plated pieces determine their value. The material itself doesn't have a lot of value on its own, as silver plate contains only small amounts of pure silver. A certified appraiser or knowledgeable antique dealer can give you an estimated value for any items that you own.
