Decoding the Date Marks

The Hermès I stamp is one of the most intriguing details for luxury handbag enthusiasts. These tiny marks, often hidden in the leather, reveal the year a bag was crafted and serve as a hallmark of authenticity. In this guide, we explore the three distinct I stamps used by Hermès over the decades and what they mean for collectors.

What Is a Hermès Blind Stamp?

Since the 1940s, Hermès has used a letter-based coding system to indicate the production year of its leather goods. Each letter corresponds to a specific year, and when the alphabet was exhausted, the maison introduced geometric symbols (like squares, circles, or stars) to differentiate cycles. This practice helps authenticate pieces and trace their history.

The Three Hermès I Stamps

I Square Stamp (2005)

If your bag features an 'I' enclosed in a square, it was crafted in 2005. This stamp is typically found on the sangles (the leather straps that wrap around the front) of Birkin and Kelly bags. The square indicates the second cycle of the alphabet, which began in 1998 with the letter A.

Beyond Birkin and Kelly, the 2005 I stamp appears on various leather goods, including wallets and belts. It is often accompanied by the craftsman's mark, a separate symbol that identifies the artisan who created the piece.

I Circle Stamp (1979)

An 'I' inside a circle dates the item to 1979, a year before the Birkin was introduced. This stamp is commonly found on Kelly, Constance, and other vintage bags, as well as small leather goods. On a Kelly, look for the circle stamp on the sangles; on a Constance, it is located on the leather zipper pull.

Plain I Stamp (1953)

The earliest I stamp, with no surrounding shape, signifies a bag produced in 1953. Due to the age, these pieces are extremely rare on the resale market. If you encounter one, it is a true vintage treasure, predating the Kelly's rise to iconic status.

Where to Find the I Stamp

The placement of the blind stamp varies by bag style. On Birkin and Kelly, it is typically on the sangles. On Constance, it may be on the zipper pull. For other items, check the interior leather pockets or the underside of straps. Always look for the accompanying craftsman's mark to ensure authenticity.

Why the I Stamp Matters

Understanding Hermès date stamps is essential for any collector. It not only tells you the year of manufacture but also confirms the bag's authenticity and heritage. Whether you own a 2005 Birkin or a vintage 1979 Kelly, the I stamp is a mark of exceptional craftsmanship and timeless elegance.

Authenticating Your Hermès

When you find an 'I' stamp, you are witnessing a piece of Hermès history. For those considering a pre-owned purchase, professional authentication services can provide peace of mind. Experts with years of experience can verify the stamp's authenticity and ensure your investment is genuine.
