Sterling vs. Plated Silver: How to Tell the Difference at Home

Guides

Sterling silver is 92.5% pure silver and has real melt value. Silver-plated items are a thin layer of silver over a base metal and are usually worth only what they look like. Telling them apart is easy once you know what to check.

Step 1 — Look for marks

• Sterling marks: "925", ".925", "STERLING", or "STER"
• British sterling: a lion passant (walking lion) hallmark
• Plating marks (NOT sterling): "EP" (electroplate), "EPNS" (electroplated nickel silver), "Silverplate", "Quadruple Plate", "A1", "Sheffield Plate"
• Lots of antique sterling has only a maker's mark — country and era matter

Step 2 — The magnet test

Real silver is not magnetic. Hold a strong magnet (a rare-earth magnet from a hardware store works) near the item:

• No pull at all — could be sterling, fine silver, or a non-ferrous base metal like brass
• Strong pull — the core is iron or steel, so it's plated, not solid silver

Step 3 — The ice test

Silver is the most thermally conductive everyday metal. Place an ice cube directly on the piece. Real silver will start to melt the ice almost immediately and noticeably faster than other metals. It's not perfect proof, but a quick screen.

Step 4 — Check for wear-through

Plated items often show brassy or coppery patches on edges, raised areas, and high-touch points. Sterling tarnishes uniformly and to a darker gray-black, but you'll never see a different metal underneath.

Step 5 — Acid test (for confirmation)

A small silver acid-test kit (under $20) tells you the actual silver content. Make a tiny scratch in an inconspicuous spot and apply the acid — color reactions tell you 925, 800, plate, or fake. This is the only fully reliable home test.

What sterling is worth

Sterling has real melt value at 92.5% × current silver spot price × weight. A heavy sterling tray can be worth hundreds of dollars in melt alone, plus craftsmanship premium for designer or antique pieces.

What plate is worth

Silver-plated pieces are typically valued for their decorative or vintage appeal, not their metal. The actual silver on a plated tray is often less than a gram total.
