Anything made by Rogers, if it doesn't say sterling or 925, will be plate. I've handled probably over 1000 miscellaneous Rogers pieces and I've never found one to be sterling. The odds are probably one in a million of finding a Rogers sterling piece. Most of the sterling pieces they made are well over 100 years old and they didn't make very many. If I have plate leftover from a lot, I'll list all of the pieces together in a lot and throw them on ebay. I add priority mail shipping for whatever box they will fit it, start auction at .99, and let it go. I have always made back over what I had into them.
