Silver has been a cherished metal for centuries, often used to craft fine jewelry, tableware, and decorative objects. When examining antique silver items, it’s essential to understand the different silver grades, which refer to the purity or content of silver in an alloy. Each grade reflects the percentage of pure silver, with the remainder typically being other metals like copper. Here’s a guide to some of the most common silver grades found in antique pieces, including 0.800, 0.925 (sterling silver), 0.935, and others.
1. Fine Silver (999 Silver)
- Purity: 99.9% pure silver
- Common Markings: "999," ".999," or simply "Fine Silver"
-
Characteristics:
- Fine silver is the purest form of silver used in jewellery and objects, containing 99.9% pure silver.
- It is very soft and malleable, making it prone to scratches and damage. Because of its softness, it’s not commonly used for objects that require durability.
- Fine silver is often used for bullion coins or collectible items where a high silver content is desired.
2. Sterling Silver (925 Silver)
- Purity: 92.5% silver, 7.5% other metals (usually copper)
- Common Markings: "925," ".925," "Sterling," or "Sterling Silver"
-
Characteristics:
- Sterling silver is the most common grade of silver found in antique items, particularly in silverware, jewellery, and decorative objects.
- The 7.5% of other metals (typically copper) added to sterling silver enhances its strength and durability while maintaining its lustrous appearance.
- Sterling silver has been the standard for centuries in countries like the UK and the US, with many historical pieces from the 19th and 20th centuries bearing this hallmark.
3. Britannia Silver (958 Silver)
- Purity: 95.8% silver, 4.2% other metals
- Common Markings: "958" or "Britannia"
-
Characteristics:
- Britannia silver was introduced in England in 1697 as a higher purity alternative to sterling silver, primarily to protect against the melting down of coinage for use in silverware.
- It is softer than sterling silver due to its higher silver content but still suitable for crafting intricate decorative pieces and high-end silverware.
- While not as widely used today, antique Britannia silver items are highly collectible and often seen in high-quality 18th and early 19th-century English silverware.
4. Coin Silver (900 Silver)
- Purity: 90% silver, 10% other metals
- Common Markings: "900," "Coin"
-
Characteristics:
- Coin silver gets its name because it was often made from melted-down coins, especially in the United States before the adoption of the sterling silver standard.
- With 90% silver content, coin silver is slightly less pure than sterling silver but was widely used in early American silverware and jewelry.
- Antique coin silver pieces are still highly valued by collectors, particularly for their historical significance in the US.
5. German Silver (800 Silver)
- Purity: 80% silver, 20% other metals (usually copper)
- Common Markings: "800" or "800/1000"
-
Characteristics:
- 800 silver is a common standard used across Continental Europe, particularly in Germany, hence the name "German silver."
- Although not as pure as sterling silver, 800 silver is still prized for its durability and appearance. It was often used in flatware, tableware, and decorative items in the 19th and early 20th centuries.
- This silver grade is often found in antique items originating from European countries like Germany, France, and Italy.
6. Swiss/French Silver (935 Silver)
- Purity: 93.5% silver, 6.5% other metals
- Common Markings: "935"
-
Characteristics:
- Silver with a purity of 93.5% is less common but is often associated with higher-end jewellery and watches, particularly from Switzerland.
- This grade of silver offers a slight increase in purity compared to sterling silver, making it slightly softer but giving it a more brilliant shine.

7. Mexican Silver (varies)
- Purity: 92.5% to 95% silver (depending on the era)
- Common Markings: "Sterling," "925," or "970" (for higher-purity Mexican silver)
-
Characteristics:
- Mexican silver is typically sterling silver, but higher grades like 970 (97% silver) are also found, particularly in vintage and antique jewellery from the early 20th century.
- Mexican silver became highly popular in the mid-20th century, known for its intricate designs and craftsmanship, particularly in the Taxco region.
8. Russian Silver (varies)
- Purity: 84% silver (875) and occasionally higher grades

Understanding the Importance of Hallmarks
Most antique silver items bear hallmarks indicating their purity, maker, and origin. These hallmarks are key to identifying not only the grade of silver but also the item's age, country of origin, and sometimes the workshop or silversmith that made it. Collectors and enthusiasts often rely on hallmark guides to verify the authenticity and value of antique silver pieces.
Conclusion
The grade of silver in antique items plays a significant role in their value, durability, and appeal. Whether it's the common sterling silver, rarer Britannia or French silver, or unique grades like German or coin silver, understanding these differences is essential for both collectors and sellers. Always check for hallmarks to determine the purity and origin of the silver, and remember that even silver of a lower grade can carry significant historical and monetary value.
