Hi, I'm looking to see if anyoe knows what this mark is and if this is silver plate...Thanks,

I'm willing to venture that this was stamped by the 'Rockford Silver Plate Co.', based on the 'J' & "G' in shields surrounding the crown and the 'R S P C'. The 'E P N S' indicates the item is composed of electro-plated nickel-silver.
