I have a 5 pc completer set of stainless steel William Rogers and Son (includes pie server, meat fork server, butter knife, gravy ladel, and sugar spoon. This is in the original blue cardboard box. There is no date on this set as far as I can tell. These have never been used and are all in excellent condition, including the box - has some "old" discoloration but completely intact. I would like to know what this may be worth should I decide to sell.
