How to identify sterling silver marks and tell them from silverplate.

Solid silver and silverplate can look the same on the table, but they are very different to a buyer. The marks on the back usually tell you which you have.

Why the marks matter

Sterling silver is an alloy of 92.5 percent silver, and pieces made from it carry value from their metal content, plus any value from the maker, design and condition. Silverplate has only a thin layer of silver over a base metal, so its value depends on design and condition alone. Most of the time, the marks stamped on the piece are the quickest way to tell them apart.

Where to look

Check the back of flatware handles, the underside of bowls, trays and candlesticks, the rim of the base, and inside lids. Use a magnifier or your phone's zoom, and angle a light across the surface so small stamps show up.

American and general sterling marks

British hallmarks

British silver usually carries a group of small stamps:

Other countries

Many countries used numbers for silver content in parts per thousand, such as 800, 830, 835 or 900, which are lower than sterling but still solid silver. Some countries had their own symbols: German silver of a certain era often shows a crescent moon and crown next to the number, and French silver uses a series of official marks, including a head of Minerva on many pieces. Older Russian silver may show the number 84, an old measure of purity. Look up unfamiliar marks in a reference before drawing conclusions.

Marks that mean silverplate

Some 19th-century makers of plated wares used small symbols that imitate British hallmarks. If the marks look like hallmarks but there is no recognizable lion, assay office and date letter, it may be plate.

Weighted pieces

Candlesticks, compotes and some bowls are often marked "Weighted" or "Reinforced". These have a thin silver shell filled with another material for stability, so only a small part of their weight is silver. Do not judge them by their weight on a scale.

Simple checks that do not damage anything

Fake and misleading marks

Marks can be faked, and silver-colored items from many places are stamped 925 without being sterling. Red flags include crude or blurry stamps, marks in unusual places, hallmarks that do not match each other, and a piece that seems light or worn through on the edges. Have anything important checked by a professional.

Photograph it for a scan and a listing

  1. The whole piece on a plain, neutral background in soft daylight.
  2. The marks, close up and sharp, with light angled across them.
  3. Any monogram, dents, repairs or worn areas.

When to get an appraisal

For large sets of sterling flatware, pieces from known silversmiths, antique hallmarked silver and anything with unclear marks, ask an independent appraiser or a specialist silver dealer. If you are thinking of selling for scrap, compare that with what the piece could fetch as a usable or decorative item first; well-designed pieces can be worth more intact.

Where WorthAI fits

WorthAI identifies the likely item, maker and pattern from a photo, gives an estimated worth with a range and a suggested asking price, reads buyer demand and shows the marketplace listings behind the estimate. Add a close-up of the marks if WorthAI asks for more detail, or tap Refine Result. WorthAI cannot test metal content, so confirm sterling with the marks above and a professional test.

Frequently asked questions

What does 925 on silver mean?

It means the item is meant to be 92.5 percent silver, the sterling standard. Marks can be faked, so treat it as a strong clue and confirm important pieces with a professional.

How can I tell sterling silver from silverplate?

Look for marks such as Sterling, 925 or British hallmarks for solid silver, and EP, EPNS, Silverplate or Quadruple Plate for plated pieces. Wear showing a different metal underneath also points to plate.

What does weighted mean on silver?

A weighted piece has a thin silver shell filled with another material. Only a small part of its weight is silver, so it is not valued by weight.

Should I sell sterling silver for scrap?

Compare first. Plain or damaged pieces may be best sold for metal value, but sets and pieces from known makers can be worth more as usable silver. Get more than one offer.
