This is the 1930's Tropical pattern by International Silver made in silver plate, meaning it is a base metal of copper, nickel and zinc and was dipped in a thin wash of silver. Silver plated items are not valuable enough to re-plate. It would only be worth doing if it were STERLING silver, which is 92.5% silver throughout. This tray has a value of $50.00 currently and re-plating it would not change that value and I would hate to see you waste your money.
