Grapes are always a plus on silverplate items, again I think we are looking at a tray made in the early 1900's mayabe Late 1800's but would bet on the latter. Trays are so plentiful and carry only little value because of how many there are out there, but amazing enough next to my teacups I have sold more trays then most items, usually with about 10 to 15 dollar tag on one that is in good condition. Boost that a bit with the facts it is grapes and a sheffield, which are usually made of really heavy gauge Nickle silver base. 20 to 25 bucks on a great flea market day.
