Look first for any markings on the item. EPNS items will usually be stamped “E.P.N.S.,” “E..P” for electroplate or “A1” for highest quality. The presence of any of these marks is a sure sign that the piece is made from EPNS.

What causes a streak of black residue on EPNs?

Silver oxidizes in the atmosphere, causing a loose black residue. On unpolished solid silver and Sheffield plate, this effect is very evident and the tissue will come away with a streak of grime. The effect is much less marked on EPNS; dirt tends to be pitted and ingrained.
