Coin silver is an alloy made up of silver and other metals such as copper, nickel, or zinc. The term “coin silver” comes from the use of this alloy in making coins in the United States during the 19th century. Coin silver typically has a silver content of 90%, with the remaining 10% made up of other metals.

The use of other metals in coin silver is important because it affects the alloy’s durability, malleability, and color. Copper is the most common metal added to coin silver, which gives it a warm, reddish hue. Nickel, on the other hand, is added to create a brighter, whiter finish. Zinc is used to create a silver alloy that is harder than pure silver; it is often used in making tableware or flatware.

The composition of coin silver is essential to its properties and how it is used. The different percentages of silver and other metals used in the alloy can affect the alloy’s color, strength, and malleability. In general, coin silver is less malleable than pure silver, which makes it less suitable for intricate designs. However, it is more durable and resistant to tarnishing, making it a popular choice for creating everyday items such as flatware and tableware.

Uses for Coin Silver

Historical uses

Coin silver has been used throughout history in a variety of applications. In the 18th and 19th centuries, it was commonly used to make silverware, such as spoons, forks, and knives. It was also used to create decorative objects such as candlesticks, picture frames, and jewelry. Coin silver was also used to mint coins in the United States until the early 1900s.

Modern uses

Today, coin silver is still used in the creation of silverware and decorative objects. It is a popular choice for creating flatware, such as dinner forks and spoons, because of its durability and resistance to tarnishing. Coin silver is also used in the creation of jewelry and is a popular choice for making vintage-inspired pieces.

Differences between Coin Silver and Sterling Silver

While coin silver and sterling silver are both silver alloys, they have some distinct differences.

Silver content

Coin silver typically has a silver content of 90%, while sterling silver has a silver content of 92.5%. The higher silver content in sterling silver makes it more valuable than coin silver.


Coin silver is generally more durable than sterling silver because of its lower silver content. The addition of other metals such as copper and nickel makes it less likely to scratch or dent. Coin silver is also more resistant to tarnishing than sterling silver.


Sterling silver is more valuable than coin silver due to its higher silver content. Sterling silver is also more widely recognized and sought after by collectors and investors. However, coin silver can still be valuable, especially if it is from a historical period or has unique features such as intricate designs or hallmarks.

Identifying Coin Silver

Identifying coin silver is essential for collectors, dealers, and buyers to determine its authenticity and value accurately. The most common way to identify coin silver is through hallmarks, which are stamps or markings on the silver that indicate its purity and origin. Hallmarks can provide information such as the silver’s maker, city of origin, year of manufacture, and purity of the silver.

Hallmarks can vary depending on the country, and some countries do not have a hallmarking system. In the United States, for example, coin silver is generally marked with the “coin” mark, which indicates its silver quality. Other marks, such as the maker’s mark or city mark, can also provide additional information about the silver’s origin and authenticity.

Another way to identify coin silver is through testing methods. Acid tests are commonly used to determine the purity of silver, including coin silver. During this test, a drop of nitric acid is applied to the silver, and the reaction is observed. If the silver turns green, it indicates that it is not pure silver. If it turns white, it means that the silver is at least 90% pure, which is the standard for coin silver.

Caring for Coin Silver

Proper care and maintenance are essential for preserving the beauty and value of coin silver. Cleaning coin silver requires a delicate touch to avoid damaging the surface or removing any patina. It is recommended to clean coin silver using a mild soap and warm water, followed by a gentle polishing with a soft cloth. Abrasive cleaners or polishing compounds should be avoided, as they can scratch the surface of the silver.

After cleaning, it is important to store coin silver properly to prevent tarnishing and damage. Coin silver should be stored in a dry, cool place, away from direct sunlight or heat. It is best to store it in a tarnish-resistant cloth or an airtight container to protect it from moisture and air.

Regular maintenance and care can help to maintain the beauty and value of coin silver for generations to come. By following these simple tips, you can ensure that your coin silver remains in excellent condition and retains its unique history and value.
