What Does IS Mean on Silverware: Understanding Marks and Their Significance

Introduction

Silverware, an elegant and timeless addition to any dining table, is often adorned with various markings to indicate its origin, quality, and value. One such marking that frequently appears on silverware is the 'IS' mark. In this article, we will explore the meaning of 'IS' on silverware, the background of the International Silver Company (hereafter referred to as ISC), and what to look for when identifying silverware markings.

Understanding the 'IS' Mark

The 'IS' mark is a designation for pieces of silverware manufactured by the International Silver Company (ISC) after 1964. This mark is a stylized 'IS' that serves as a logo and a symbol of the brand.

The IS mark, while recognizable, does not provide any information about the purity or value of the silver used in the piece. Unlike sterling silver, which is clearly marked with 'STERLING' or '.925', IS silverware is simply identified by this distinctive mark.

If you come across silverware marked with the 'IS' symbol, it signifies that the piece is from the International Silver Company and was made after 1964. This mark is your assurance that the item is genuine and part of the International Silver collection.

The International Silver Company (ISC)

Established in 1840, the International Silver Company (ISC) has a rich history synonymous with American craftsmanship and elegance. Over the years, ISC has garnered a reputation for producing high-quality, luxurious silverware that has been sought after by collectors and enthusiasts worldwide.

The IS marking that you see on silverware is a straightforward way to identify pieces from the ISC. This marking can be found on both modern and vintage pieces, making it easier for collectors and consumers to confirm the brand and the period of manufacture.

What Rogers Brothers Markings Mean

In addition to the IS mark, you may come across the Rogers Brothers mark on silverware. It's essential to understand that these marks are distinct and should not be confused with the IS mark. Rogers Brothers was another notable silver company, known for their high-quality workmanship and distinctive designs.

When you see a marking that says 'Rogers Brothers', it indicates that the piece was manufactured by that specific company. Just like the IS mark, 'Rogers Brothers' simply denotes the brand and does not provide information about the silver's purity or value.

How to Identify Genuine Silverware

To fully appreciate the significance of the 'IS' mark and other silverware markings, it's helpful to understand the key factors in identifying genuine silverware.

Markings and Their Meanings

- IS Mark: Denotes International Silver Company after 1964. - STERLING or .925: Indicates sterling silver with a purity of 92.5% silver and 7.5% other metals. - Rogers Brothers: Marks pieces manufactured by Rogers Brothers.

Other Indicators of Authenticity

- Patent Numbers: Check if the piece has any patent numbers, as these are often included on genuine designs. - Weight: Genuine silverware tends to be significantly heavier than items made from other metals. - Patina and Condition: Authentic silverware often has a natural patina, and the condition should be consistent with the piece's age and usage.

By paying attention to these details, you can more confidently identify the authenticity and value of your silverware, ensuring you own pieces that stand the test of time.

Conclusion

The 'IS' marking on silverware is a clear and recognizable symbol of the International Silver Company's silver manufacturing. While it does not indicate the purity or value of the silver, it is a valuable identifier for collectors and consumers. By understanding the history of ISC and the significance of the IS mark, you can better appreciate and safeguard your silverware collection.

Whether you are a seasoned collector or a new enthusiast, understanding the markings on your silverware can enhance your appreciation of these elegant and valuable items. Remember, the IS mark is but one of many features to consider when evaluating your silverware collection.
