American Silver History

What is coin silver?
History, marks, and value.

Coin silver — 90% pure, made literally from melted US coins — was the American silver standard before sterling. Inherited pieces by documented early silversmiths can be quite valuable.

An Older American Standard

Coin silver: the pre-sterling standard in American estates

Coin silver is one of the more rewarding discoveries in an inherited silver collection. It predates sterling in America, it has real silver content, and — when made by a documented early silversmith — it can be genuinely valuable as an antique in ways that ordinary 20th-century sterling rarely is. If your family has deep American roots, especially in the early 19th century, some of your inherited silver may be coin silver.

What coin silver is

Coin silver is an alloy of 900 parts silver per 1000 — 90% pure silver, 10% copper. It is slightly less pure than sterling (925 parts per 1000, or 92.5%), but still well above the 80% threshold where a metal begins to lose its "silver" identity. The visual difference between coin silver and sterling is minimal; coin silver can be very slightly warmer in tone due to the higher copper content, but both look like fine silver to the eye.

The name comes from the literal origin of the metal. From the early 1800s through the 1860s, American silversmiths obtained their working material by melting down US silver coins, which at the time were 90% silver by law. A silversmith with a commission for a tea pot or a set of flatware would accept silver dollars, half-dollars, and smaller coins from the client — often the client's own coins — and melt them into ingots for fashioning into the finished object. The finished piece inherited the 90% fineness of the source coins.

The historical context

American coin silver was produced primarily between about 1800 and the late 1860s. Earlier colonial silver (17th and 18th century) used somewhat variable standards, often close to coin silver purity but not formally regulated. The 19th century was the great age of American coin silver — the period when silversmithing was a recognized skilled trade in cities throughout the new republic.

Coin silver lost ground to sterling starting in the 1860s. Tiffany & Co. adopted the English sterling standard in 1851. Gorham followed in the 1860s. By the 1870s, most major American silver producers had shifted to sterling, and coin silver production dwindled. Some Southern silversmiths continued producing coin silver into the 1870s and occasionally later, but for most of American silver by the late 19th century, the word "sterling" had replaced "coin" on new pieces.

Coin silver marks

Unlike English hallmarks, American coin silver marks are simple. The most common fineness marks include:

"Coin" — the most direct mark, typically in italics or capitals. Indicates the piece meets the coin silver standard.

"Pure Coin" — a variation emphasizing the fineness.

"Standard" — used by some makers to indicate the piece meets the standard silver fineness, essentially equivalent to "coin."

"C" — abbreviation for "coin."

"D" — abbreviation for "dollar," indicating that silver dollars were the source of the metal. A mark associated with some Southern silversmiths.

"900" — numerical fineness mark, 900 parts per thousand. Used less often in America than in France and some other countries.

These fineness marks are usually accompanied by a maker's mark — the silversmith's full name, last name, or initials, sometimes in a rectangle or oval. Pattern names and city marks are rare; most coin silver identifies only the maker.

Major regional schools

Coin silver collecting is deeply regional. Specific cities and regions produced distinct schools of silversmithing with their own style, forms, and specific makers. Key areas:

Boston and New England. Home to colonial silversmiths like Paul Revere, whose work transitioned into the coin silver era. Boston coin silver by documented makers is actively collected.

New York. A major silversmithing center throughout the 19th century with many documented makers whose marks appear in inherited New York collections.

Philadelphia. Another major center, with Philadelphia coin silver notable for fine flatware and holloware by well-documented makers.

Baltimore. A significant Southern-adjacent center. Baltimore repousse work began in the coin silver period.

Southern coin silver. Charleston, Savannah, New Orleans, Nashville, and other Southern cities produced distinctive coin silver, often in the form of beakers, julep cups, small pitchers, and simple flatware. Southern coin silver is particularly collected, with rare documented regional makers commanding significant premiums.

Value of inherited coin silver

Coin silver has the same general melt-value range as sterling. At $28/troy oz silver spot, coin silver is worth roughly $25.20 per troy ounce of piece weight. A typical coin silver teaspoon (1-1.5 troy ounces) has $25-40 in melt content. A coin silver tablespoon (2-3 troy ounces) has $50-85 in melt. A coin silver beaker or small pitcher (4-8 troy ounces) has $100-225 in melt.

On top of melt, documented American coin silver by identified makers commands significant premiums. Typical values:

Unsigned or unattributed coin silver flatware. Usually sells near melt value — $30-100 per piece depending on size.

Attributed coin silver flatware by documented makers. Often $75-300 per piece for tablespoons and ladles; less for teaspoons.

Coin silver holloware by known makers. Beakers and small pitchers $200-1,000. Tea pots and larger forms $500-3,500.

Important pieces by premier early silversmiths. Can reach $5,000-20,000 for documented pieces with fine form and provenance, and higher for exceptional examples by premier makers like Paul Revere, John Coney, or other major colonial and Federal silversmiths.

Southern coin silver by rare regional makers. Often outperforms Northern equivalents. Julep cups, beakers, and tea pots by documented Southern silversmiths can reach $2,000-10,000 or more.

Why coin silver collectors differ from sterling collectors

The coin silver and sterling markets have different buyer profiles. Coin silver collectors are typically antique-furniture-and-decorative-arts collectors focused on the Federal and antebellum periods. They value the hand-wrought construction, the documentation of early American silversmithing, regional schools, and pieces with provenance. Sterling collectors, by contrast, often focus on 20th-century patterns, English hallmarked silver, or premier 20th-century American makers.

This difference means that inherited coin silver often finds its best market at auctions specializing in American furniture and decorative arts, while 20th-century sterling flatware sells through silver specialists and estate dealers. Matching the piece to the right buyer is part of what separates a good outcome from a mediocre one.

Photo Tip

Photograph coin silver marks in detail — the fineness mark, the maker's name, and any location or date information. Also photograph the hand-wrought surfaces (hammer marks, hand-cut engraving, slightly irregular forms) which help confirm early production. Weight and size measurements help specialists estimate silver content and attribute the maker.

An Honest Take

What usually isn't valuable

Coin silver can be valuable, but not every piece that looks early is a collector prize. Here is what commonly sells at or near melt.

Unattributed or illegible marks

Coin silver pieces with worn, illegible, or missing maker's marks sell near melt value only. Without an identified silversmith, buyers treat the piece as silver content rather than as a documented antique. Even a beautifully hand-wrought coin silver piece loses most of its collector premium without attribution — the maker is a large part of what gives these pieces value.

Damaged or heavily repaired coin silver

Coin silver that has been dented, re-soldered, or significantly repaired loses much of its value. Early silversmithing involved labor and skill that is part of the piece's appeal; visible later repairs interrupt the original work and reduce collector interest. Damaged coin silver typically sells at melt or just above, even by documented makers.

Heavily monogrammed or engraved pieces

Coin silver flatware often carried period family monograms, which usually add rather than subtract value when period-appropriate. Later 20th-century monograms added to coin silver pieces, or heavy engraving that was not part of the original piece, reduce value. Period presentation inscriptions (marriage, commemoration) to documented recipients can actually add value; generic later additions do not.

Coin silver flatware in broken sets

A partial coin silver flatware set — say, four of a dozen original teaspoons surviving — is worth less per piece than a complete set would be. Buyers interested in coin silver flatware generally want documented multi-piece groupings, and broken sets sell as individual pieces at melt or modest premium rather than as a functional service. Complete matched coin silver services are rare and command premiums.

Common Questions

Frequently asked about coin silver

Coin silver is an alloy of 900 parts silver per 1000 — 90% pure silver, 10% copper — that was the American silver standard from roughly 1800 to the late 1860s, before sterling (925) became dominant. The name comes from its origin: American silversmiths literally melted down US silver coins, which at the time were 90% pure, and refashioned the metal into flatware, tea pots, and other objects. Coin silver has real precious metal content and is a genuine antique category, distinct from both sterling and silverplate.
Coin silver marks include the word "Coin," "Pure Coin," "Standard," the letter "C" or "D" (D for dollar, referring to the coins that were melted), and the number "900" or "900/1000." A maker's name or initials usually appears alongside the fineness mark. Coin silver is unlikely to be marked "Sterling" or "925" — those are later standards. If you see a clearly pre-1870 American piece with a maker's name and one of the coin silver fineness marks, you have coin silver.
Coin silver was the dominant American silver standard from approximately 1800 through the late 1860s. Earlier American silver (colonial era, through the late 1700s) used somewhat variable standards but was often close to coin silver purity. Sterling began replacing coin silver in the 1860s as Tiffany, Gorham, and other major firms adopted the higher standard. By the 1870s, most American silver was sterling, and coin silver production had largely ended. Some Southern silversmiths continued using coin silver into the 1870s.
Yes, often quite valuable. Coin silver has real silver content (90% vs sterling's 92.5%), so it has the same general melt-value range as sterling. On top of metal value, early American coin silver by documented makers is actively collected as antiques. Pieces by major early 19th century silversmiths in cities like Boston, Philadelphia, New York, Baltimore, and Charleston can sell for $500-5,000 or more depending on maker, form, and condition. Southern coin silver is particularly collected, with rare regional makers commanding significant premiums.
The main difference is purity: coin silver is 90% pure, sterling is 92.5% pure. The visual difference is minimal — both look the same to the eye, though coin silver can be slightly warmer in tone due to higher copper content. The collector markets differ more than the metal. Sterling collectors generally focus on 20th-century American patterns, English Georgian hallmarked silver, and premier-maker holloware. Coin silver collectors focus on early American silversmiths, regional schools (particularly Southern coin silver), and period pieces. A coin silver piece by a known early maker is typically rarer than a sterling piece by a 20th-century factory.
Most surviving coin silver consists of flatware — tablespoons, teaspoons, ladles, serving pieces — because these were the most common household silver items of the early 19th century. Coin silver holloware is less common but highly collected: tea pots, sugar bowls, creamers, small bowls, and beakers by documented makers appear occasionally in estate inventories. Beakers and julep cups were particularly associated with Southern coin silver. Church silver (communion cups and flagons) from this period is another specialty category. Nearly all coin silver is hand-wrought rather than machine-made, adding to its collector appeal.
