Many pieces of electroplate are simply marked EP, EPNS (Electroplated Nickel Silver), or EPBM (Electroplated Britannia Metal). Sometimes the mark A1 is also found; this denotes the best quality. Many firms in the nineteenth and twentieth century have used these marks. In addition, firms often stamped their name, initials, trade mark or symbols on electroplated goods. Some firms used different marks for holloware and flatware. As with nickel silver, marks on nineteenth century electroplate often consist of a row of stamps superficially similar to silver hallmarks; many incorporate the firm’s initials.

Also some electroplaters marks even include a crown symbol; a flagrant imitation of a silver mark. Under the Acts of Parliament of 1773 and 1784 it was illegal to use marks consisting of letters on silver plated wares, whilst the crown mark, being the Sheffield Assay Office town mark for silver, was also illegal if stamped on silver plated or non precious metals, under the terms of the 1784 Act and an Act of 1844. These illegalities were tolerated in the second half of the nineteenth century, until in 1896 Sheffield Assay Office threatened firms using the crown mark with prosecution. This action seem to have been effective, and firms like Elkingtons stopped using the crown mark on plated wares shortly afterwards.
