Hi welcome to the forum.
EPNS A in gothic letters for: Electro Plated Nickel Silver . The A is a quality indicator..EPNS stands for "Electro Plated Nickel Silver". Nickel Silver (or occasionally stainless steel) is the base metal onto which silver is plated. Despite its name, Nickel Silver contains no silver at all, but is an alloy of Nickel, Zinc & Copper.
