What 800 Silver Means on Continental Antique Pieces

Turn over a German cake fork or an Italian bonbon dish and you will often find a tiny "800" stamped beside a crescent moon or a star. Buyers at fairs regularly pass these pieces by, assuming the number means plated or second rate. It does not. 800 silver is solid silver, simply made to a lower standard than British sterling.

Understanding that number changes how you price, clean and insure Continental pieces. Below I explain what the mark guarantees, which countries used it, how to read the marks that sit beside it, and what it means for value at auction and on the scales.

What the 800 Mark Guarantees

The number is a fineness mark expressed in parts per thousand. An object stamped 800 contains at least 800 parts of pure silver in every 1,000, or 80 percent. The remaining 20 percent is usually copper, added for hardness.

British sterling is 925, or 92.5 percent. Britannia standard is 958. So an 800 piece contains roughly 13 percent less silver by weight than a sterling piece of the same size. It is still solid throughout, which separates it entirely from Sheffield plate or electroplate, where a thin layer of silver covers a base metal. If you are unsure which you have, our guide to telling Sheffield plate from electroplate covers the surface clues.

Where 800 Silver Was Made

The 800 standard was common across much of mainland Europe from the mid nineteenth century onward. The table below shows the countries you will meet most often and the standards they used alongside it.

The Netherlands and Belgium favoured 833 and 835, and Scandinavian makers often used 830. All of these sit in the same broad family, below sterling but well above anything plated.

Reading the Marks That Sit Beside the Number

A fineness number on its own tells you the standard, but the marks around it tell you where and roughly when the piece was made. Use a 10x loupe and good daylight, and work through them in order.

1. Find the fineness. Look for 800, 830, 835 or similar, sometimes inside a shield or lozenge.
2. Find the national mark. A German crescent and crown confirms post-1888 German work. An Italian lozenge with a star dates the piece after 1968.
3. Find the maker's mark. German silver usually carries the maker's name or initials, such as Wilkens or Koch and Bergfeld. Italian lozenges include a registration number and a province abbreviation, for example "FI" for Florence or "MI" for Milan.
4. Look for retailer stamps. Some pieces sold abroad carry a shop name as well, which can add interest for collectors.

The process is the same discipline you would apply to British pieces, and our guide to reading hallmarks on old silver walks through the British side if you collect both.

Is 800 Silver Worth Less Than Sterling

By metal content, yes. By antique value, not necessarily. A Jugendstil fruit bowl in 800 by a known German maker can comfortably outsell a plain Victorian sterling bowl of the same weight, because design and maker drive the price once a piece rises above scrap.

For plain, unattributed items, metal value sets the floor. To work it out, weigh the piece in grams, divide by 31.1 to get troy ounces, then multiply by 0.8 and by the current spot price. A 250 gram dish is about 8.04 troy ounces of alloy, or 6.43 ounces of pure silver. At a spot price of $30 an ounce, the melt value would be around $193. Dealers buying for scrap usually pay 70 to 85 percent of that figure.

When you sell, say what the piece is plainly. A listing that reads "German 800 standard, Koch and Bergfeld, Bremen, about 1900" attracts specialist buyers, while "silver coloured dish" invites scrap offers. Include the weight in grams and clear photographs of the marks, because serious bidders want to check them before they commit.

Weighted pieces, such as candlesticks with a filled base, need care. The filling can account for most of the weight, so never apply melt calculations to a loaded item.

Testing a Piece When the Mark Is Worn

Marks on spoon stems and fork shoulders often wear flat after a century of polishing. If you cannot read them, there are a few sensible checks before you pay a silver price.

• Magnet test. Silver is not magnetic. A strong neodymium magnet that grabs the piece rules out solid silver at once.
• Look for wear through. Plated pieces show a yellow or grey base metal on high points and edges. Solid 800 wears evenly and stays silver coloured.
• Acid testing. A dealer or assay office can test a small scratch on a hidden area. Kits sold for home use are cheap but leave a mark, so practise on a scrap piece first.
• Professional analysis. Many larger dealers now use handheld XRF analysers, which read alloy content without any damage and take under a minute.

Caring for Lower Standard Continental Silver

The extra copper in an 800 alloy makes it tarnish a little faster and sometimes develop a warmer, slightly pink tone after heavy polishing. That tone is called firestain when it comes from the original manufacture, and it should not be polished away aggressively.

Clean with a soft cotton cloth and a gentle silver polish, rinse in warm water, and dry immediately. Avoid dip cleaners, which strip the darker recesses that give chased and embossed work its depth. Store pieces in anti-tarnish cloth bags, and keep them away from rubber bands, felt that contains sulphur and oak cabinets, all of which speed up tarnish.

Frequently Asked Questions

Is 800 silver real silver?

Yes, it is solid silver containing 80 percent pure silver and 20 percent other metals, usually copper. It is a recognised standard across Europe and is not plated.

Can 800 silver be called sterling?

No, because sterling requires at least 92.5 percent silver. In the UK it is also illegal to describe an item as sterling unless it meets that standard.

Why does Continental silver tarnish so quickly?

The higher copper content reacts more readily with sulphur in the air. Regular gentle cleaning and storage in anti-tarnish bags slows the process considerably.

The Takeaway

An 800 mark is not a warning sign. It tells you the piece is solid silver made to a Continental standard, and the marks beside it tell you where and when. Judge good pieces on maker and design, use melt value only as a floor for plain items, and care for them gently so the alloy keeps its depth.
