Sterling Silver Markings: How to Tell Sterling From Plate

The quick answer

Sterling is stamped STERLING or 925 in America, or with a lion passant in Britain. Anything stamped EPNS, A1, Quadruple Plate, Silver Soldered or a plate maker's name such as 1847 Rogers Bros. is silverplate. The difference matters: sterling sells for close to its silver weight, while plate sells for a small fraction of that.

What each stamp means

A maker's name, pattern number or patent date is not a silver standard. Read the standard mark first, then the maker.

Sterling mark checklist

• Find every mark: check underside, handle backs, rims, lids, clasps, bails, and feet.
• Separate metal standard from maker: 925 or STERLING is different from a company name or pattern number.
• Read country clues: British marks often include standard, city, date letter, and maker. American pieces may read STERLING plus maker. Mexican pieces often include 925, MEXICO, Taxco, or maker/shop codes.
• Check for plate language: EPNS, EP, A1, silver soldered, plated, quadruple, and hotel plate usually indicate silverplate.
• Weigh the object: sterling value is affected by weight, but weighted candlesticks, knives, and filled pieces are not solid sterling.
• Inspect condition: dents, worn plating, splits, solder repairs, missing pieces, and heavy polishing matter.

No marks, or marks you can't read?

• Look at the high points. On plate, the silver wears through on handle tips, rims and feet, showing yellow brass or grey base metal. Sterling wears but stays the same colour all the way through.
• Try a magnet. Silver isn't magnetic, so a strong pull means steel or nickel underneath. No pull proves nothing on its own: brass and nickel silver aren't magnetic either.
• Feel the weight and the edges. Plated hollowware is often light with crisp seams; weighted pieces feel heavy for their thin walls.
• Ask for a test. A jeweller or appraiser can confirm the metal with an acid or XRF test, which is more reliable than any home check.

Value drivers after the mark

• Metal content: solid sterling differs from weighted, filled, plated, or mixed-material pieces.
• Maker: Tiffany, Gorham, Georg Jensen, important British makers, regional coin-silver makers, and notable Native American or Taxco makers need closer review.
• Object type: flatware services, trays, tea sets, hollowware, jewelry, and souvenir spoons have different markets.
• Completeness: full services and matched sets can behave differently from single odd pieces.
• Condition: monograms, dents, splits, worn details, missing lids, and repairs can affect value.
• Market demand: most sterling flatware sells at auction for about 80% of its silver value; Tiffany and Georg Jensen often sell for more. See what sterling flatware sells for.

What auction evidence does not prove

A similar mark does not mean a similar value. Auction records are evidence to interpret. Condition, authenticity, maker, form, weight, completeness, repairs, provenance, and current demand can materially change value.

When to use the free screener

Use the free screener when you have clear mark photos and need quick triage: sterling or plate, likely object category, whether the item deserves deeper research, and which appraisal path fits.

When to get a professional appraisal

Use a professional appraisal for full services, important makers, estate groups, Native American or Taxco jewelry, old coin silver, insurance needs, donation questions, or anything with uncertain authenticity. For formal use, review qualified appraisal options.

Photo checklist

• Whole object from front, back, side, top, and underside.
• Sharp close-ups of every mark, not just the word STERLING or 925.
• Scale photo with ruler and written measurements.
• Weight, with a note if the piece is weighted, filled, attached to porcelain, or mixed with another material.
• Close-ups of dents, splits, solder, worn plating, monograms, missing parts, or repairs.
• Photos of storage chest, receipts, family notes, or old appraisal paperwork.

Silver standards to know

The FTC's jewelry guides in 16 CFR 23.0 include flatware, hollowware, and other silver products within the covered scope, and 16 CFR 23.5 addresses silver-content representations. That is why mark reading should separate sterling, coin silver, plated terms, and mixed-material construction.

FAQ

Is 925 always sterling silver?

925 is a sterling-standard mark when genuine, but marks can be copied or applied to low-quality pieces. Check construction, wear, maker, and test results when value matters.

What does EPNS mean?

EPNS usually means electroplated nickel silver. It is silverplate, not solid sterling.

Are monograms bad for value?

Not always, but monograms can reduce demand for some flatware and hollowware. Important makers or strong forms can still have market value.

Should I polish silver before appraisal?

Light dusting is fine. Avoid heavy polishing because it can soften marks, remove detail, and hide condition clues.
