Sterling or Silverplate: How to Read the Marks

Nearly every estate in Southern California holds a silver chest, and nearly every family opening one asks the same question: is this actually silver, or just silver colored? The two look identical across a table. The answer lives in small stamped marks on the backs of the handles and the undersides of the hollowware, and reading them takes about a minute once you know the vocabulary. This guide teaches that vocabulary, then walks through the two constructions that fool the kitchen scale, what the metal itself is worth as of this writing, and the short list of patterns that sell for real multiples of their weight.

Start on the back of a spoon

Pick up a fork or spoon rather than a knife, for reasons the knife section below makes clear, and read the back of the handle in good light. American solid silver is almost always marked in plain words or numbers: STERLING, 925, or .925, meaning 92.5 percent pure silver, often beside a maker’s name such as Gorham, Tiffany & Co, Reed & Barton, Wallace, Towle, or Whiting. English silver speaks in pictures instead: the mark that matters is the lion passant, a small walking lion, stamped alongside city and date letters. Continental pieces marked 800, 830, or 900 are solid silver too, just at a lower fineness than sterling. Everything else in the drawer is speaking the language of plate.

The mark that fools families every week

1847 Rogers Bros deserves its own paragraph, because it is the single most misread mark in American silver. The 1847 is the year the Rogers brothers founded the firm, not the year your set was made, and every 1847 Rogers Bros piece ever produced is silverplate rather than sterling. The IS often stamped beside it stands for International Silver, the plate parent company, not for any grade of silver. None of this makes the set worthless as a thing to eat with, and plenty of families keep theirs for exactly that. But plate carries essentially no metal value, and knowing that before anyone quotes you a number is the whole point of reading the mark yourself. One more wrinkle from the other direction: STERLING stamped on a costume brooch is usually a wartime date rather than a contradiction, a story covered in our costume jewelry marks guide.

The knife problem, and the weighted pieces

Here is the fact that surprises people most: the heaviest-feeling pieces in the chest contain the least silver. Nearly all sterling place knives are hollow-handled, two thin stamped sterling shells joined around a core of cement or pitch, finished with a stainless steel blade. Auction catalogs describe sets in weighable troy ounces and exclude the knives entirely for exactly this reason. The same construction hides in the hollowware: candlesticks, compotes, and trophies marked WEIGHTED or REINFORCED are a thin sterling skin over a filled core, and their silver content is a small fraction of what the piece registers on a scale. A set’s gross weight always overstates its silver, sometimes dramatically, and any reading of a chest that starts with the bathroom scale starts wrong.

What the metal floor looks like in 2026

If the marks say sterling, the set has a floor price set by its metal, and that floor has moved. Silver spot was $66.52 per troy ounce on August 12, 2026, roughly double where it started 2025. The arithmetic is simple: weighable troy ounces, knives and weighted pieces excluded, times 0.925, times the day’s spot. A typical sterling service for eight, knives excluded, carries somewhere around 50 to 80 weighable ounces, which at that August 12, 2026 spot price works out to roughly $3,100 to $4,900 in metal alone. Refiners and scrap dealers typically settle at a percentage of melt rather than all of it, since refining and reselling cost money.

The doubling matters for a second reason: it quietly rewrote every old auction result for ordinary patterns. Mid-tier sterling has historically sold at melt plus 20 to 50 percent. A 153-piece Gorham Chantilly service with 128.88 weighable ounces realized $2,560 at Case Antiques in July 2020, when spot sat near $19; that same weight of sterling melts to roughly $7,900 at August 2026 spot. So a pre-2025 comp is not what a set is worth today, and for common patterns the honest 2026 answer is that weight now matters more than the pattern name. That raised floor is good news for most families, and it comes with one warning, which is the next section.

The patterns that beat melt

A short list of patterns sells well past the metal, and the entire job of reading the chest is making sure one of them does not leave in a scrap bag. These are realized auction results, each with its date, because in this market the date is part of the number.

Read those numbers with 2026 eyes. Tiffany Audubon is the standout: the May 2025 Doyle result ran roughly four times melt on its sale date and still sits near twice melt at August 2026 spot. Chrysanthemum tells the more sobering story: that 130-piece service weighed 205.63 weighable ounces, which melts to roughly $12,700 at August 2026 spot, so even a five-figure 2022 result now runs only modestly ahead of its own metal. Georg Jensen carries an international collector base at around $80 a piece for Acorn, and Gorham Martele, the hand-hammered art line, is the reason nothing marked Gorham should ever be scrapped unexamined: Martele is priced by what it is, not what it weighs. Collectors also chase Whiting Lily, Gorham Versailles, and Tiffany English King, though we will not put numbers on those here because we have not verified recent realized results for them.

To find your own pattern’s name, the standard tool is the pattern database at Replacements, which can match a photograph of a handle to a named pattern. Use it for identification only: its listed prices are retail asking prices for individual replacement pieces, not what a set brings when it sells.

Monograms

Most older sterling carries a script initial or three, and the internet is full of confident percentages about what that costs. We will not repeat them, because the sources genuinely conflict. What is safely true: a monogram narrows the retail audience somewhat on collectible patterns, it changes nothing about the metal, and on some period pieces the original owner’s initials read as history rather than damage. The one clear rule is about removal. Grinding a monogram out thins the silver and leaves a dished spot, and it almost always does more harm than the letters ever did. Leave the initials exactly as you found them.

Do not polish anything

What to do with the chest

Photograph the marks on the backs of two or three different pieces, one wide shot of the open chest, and any pattern name printed inside the lid, all in daylight. Count the place settings and note whether knives make up much of the set. Then text the photos to (949) 449-1255 and a real person will tell you what the marks say, sterling or plate, and where the pattern sits in the market, usually the same day and always free. Across Southern California we do the same reading in person: we come to the house, sort sterling from plate from weighted pieces at the kitchen table, and explain the market as we go. On the silver itself we identify and advise, and when a set should sell we will say so plainly and point you toward a reputable silver specialist. And because the chest almost never surfaces alone, the estate around it gets a knowledgeable read the same visit, with a real offer on what we can place. Sometimes the honest answer is that the chest holds plate and memories. When it holds a Jensen ladle, you will know before it goes anywhere near a scrap scale.
