American Silver Maker’s Marks: Complete Identification Guide

Authentic American silver can be identified by locating specific maker’s trademarks (like Gorham’s lion-anchor-G or Tiffany & Co.’s strict block lettering) and verifying the metal purity stamp. Unlike British silver, which uses a date letter system, American pieces typically feature the word STERLING or the number 925 (for 92.5% purity) stamped directly on the base or handle, standard after 1868.

Imagine you are at a dusty estate sale in Virginia. You pick up a heavy, tarnished serving spoon. It feels substantial in your hand, cool to the touch. You turn it over, squinting at the tiny, worn impressions on the back of the handle.

Is it a $5 silver-plated piece of junk, or a rare $500 coin silver treasure from the 1840s? The difference lies entirely in decoding those tiny symbols.

How Do I Find the Maker’s Mark on American Silver?

Locating the mark is your first step in the attribution process. American silversmiths were generally consistent with placement, but wear and tear can make them elusive.

On flatware (spoons, forks), look at the back of the handle or the neck (where the bowl meets the handle). On holloware (teapots, bowls, trays), check the underside of the base.

You are looking for three distinct elements:
1. The Maker’s Mark: A symbol, initial, or full name (e.g., Paul Revere used a simple rectangle with “REVERE”).
2. The Purity Mark: “Sterling,” “925,” or “Coin.”
3. The Pattern Number: Often a 3-4 digit number used for cataloging.

What Are the Most Valuable American Silver Marks?

Not all silver is created equal. While the melt value of sterling silver provides a baseline, the collector market pays premiums for specific prestigious makers.

Gorham Manufacturing Co.
One of the most prolific and collectible American makers. Look for a lion (facing right), an anchor, and a capital ‘G’. If you see these three symbols, you have a piece of history.

Tiffany & Co.
The gold standard—or rather, the silver standard. Tiffany marks are text-heavy. Look for “TIFFANY & CO.” accompanied by “MAKERS” and “STERLING SILVER.” The initial of the company president often appears, helping date the piece (e.g., an ‘m’ for Moore, 1873-1891).

Kirk & Son
Famous for their intricate “Repoussé” patterns (floral designs pushed out from the back). Their marks clearly state “S. KIRK & SON.”

Identifying these marks manually can take hours of flipping through reference books. Using the Antique Identifier app, you can simply take a photo and get an instant result, linking your item to sales records and history immediately.

Is My Item “Coin Silver” or “Sterling Silver”?

This is the most common confusion I see in my shop.

Coin Silver (Pre-1868)
Before the Sterling standard was adopted in the US, silversmiths melted down actual currency to make objects. This is known as “Coin Silver” and is usually 90% pure (marked 900/1000).

• The Mark: Look for the word “COIN,” “PURE COIN,” “DOLLAR,” or simply the maker’s name/initials without the word Sterling.

• The Value: Often rarer than sterling due to age and historical significance.

Sterling Silver (Post-1868)
After 1868, major US manufacturers adopted the British standard of 92.5% purity.

• The Mark: The word “STERLING” or the number “925” is mandatory.

If a piece is marked “EPNS,” “A1,” or “Triple Plate,” it is silver plate (base metal coated in silver). These items have little intrinsic metal value compared to solid silver.

How Does Condition Affect the Appraisal Value?

When determining fair market value or an auction estimate, condition is paramount. However, “cleaning” your silver improperly can destroy its value instantly.

Provenance (the history of ownership) adds value, but physical state dictates the price ceiling.

Red Flags regarding Condition:

• Over-polishing: If the high points of the design are worn down to a dull gray base metal, it’s likely worn-out plate or damaged sterling.

• Monogram Removal: A thin spot in the center of a piece suggests a monogram was buffed out. This lowers the value significantly.

• Salt Corrosion: Black, pitted spots often found in salt cellars. This is permanent damage and requires professional restoration or conservation.

Pro Tip: Never use chemical dips on antique silver. They strip the “patina”—the dark oxidation in the crevices that highlights the pattern details.

This cautionary approach is similar to what we cover in our guide on Antique Teapot Identification: Finding English Silver and Ceramic Marks, where surface condition is equally critical.

Can I Identify a Fake Silver Mark?

Forgery detection is an art form, but there are tell-tale signs of fake assay marks or “pseudo-hallmarks.”

Many silver-plated items from the late 19th century used marks that looked like English hallmarks (a lion, a head, a letter) to deceive buyers.

The “Pseudo-Hallmark” Test:
If you see a row of symbols that look official but do not include the word “STERLING” or “925,” be highly suspicious. American companies like Meriden Britannia Co. used complicated symbols on silver plate to mimic the prestige of solid silver.

Furthermore, if the mark looks cast (soft, blurry edges) rather than stamped (crisp, sharp edges where metal was displaced), it may be a reproduction.
