Sterling vs. Silver Plate: How to Tell the Difference
Is it sterling or silver plate? Check marks, wear, magnet response and weight, understand EPNS and A1 stamps, and learn why the difference matters for value.

A tray, teapot or box of cutlery looks silver — but is it solid sterling or a thin plated layer over base metal? The difference can mean many times the value.
What's the difference?
- Sterling silver is 92.5% pure silver alloyed with other metals (usually copper). It's silver all the way through.
- Silver plate is a thin layer of silver bonded over a base metal (copper, nickel silver, Britannia metal).
Check the marks first
Sterling indicators:
- "Sterling", "925", "Sterling silver"
- British hallmarks including the lion passant
- Purity numbers like 800, 830, 835, 900 (continental silver — lower than sterling but solid silver)
Plate indicators:
- EPNS, EP, EPBM, EPC
- "Silver plate", "Silverplate", "Quadruple plate", "Triple plate"
- A1, AA, or "Sheffield" without hallmarks on later pieces
- Maker names known for plate
See the full silver hallmarks guide.
Look for wear
Plate wears through on high points — edges, handles, the backs of spoon bowls — exposing a yellowish (copper or brass) or gray base metal underneath. Sterling just shows softened detail.
Magnet test
Silver isn't magnetic. If a strong magnet sticks, the item isn't solid silver (though many plated items also don't stick, so this only rules things out).
Weight and feel
Solid silver pieces of the same size often feel heavier than plated ones with a light base metal, though this varies by design.
Other tests
Acid tests and electronic testers can confirm silver content, best done by a jeweler or dealer. See how to test silver at home for safe home checks.
Why it matters
- Sterling has a melt-value floor and collectible value on top.
- Plate is usually worth much less, unless it's a fine early piece, by a notable maker, or decorative.
Old Sheffield plate (silver fused onto copper, made before electroplating) is a separate, collectible category.

Frequently asked questions
Does silver plate have any value?
Some — decorative and high-quality pieces sell — but generally far less than sterling.
What does A1 mean on silverware?
It's a quality grade for silver plate, not a sterling mark.
Can sterling silver be unmarked?
Yes, older or foreign pieces sometimes are. A professional test can confirm.
