Decoding Hermès Your Bag

Every Hermès handbag carries a discreet yet powerful set of markings hidden within its interior. These stamps are not merely decorative; they serve as the maison's secret language, revealing the year of creation, the artisan behind the leather, the specific material used, and even whether the piece was a bespoke commission. For collectors and connoisseurs, understanding these symbols is essential to authenticating and dating a bag. This guide deciphers the meaning behind Hermès stamps, from the earliest letters to contemporary codes.

The Evolution of Date Stamps

Hermès has employed a letter-based system to indicate the year of manufacture since the mid-20th century. The oldest known date letter is 'T', introduced in 1964. Over the decades, the format has evolved, reflecting the house's commitment to both tradition and clarity.

1945–1970: The Early Years

During this period, Hermès used a variety of symbols and letters, often without a uniform enclosure. The system was less standardized, making dating these early pieces a challenge for even seasoned experts.

1971–1996: The Circle Era

In 1971, the brand introduced a more systematic approach: date letters were placed in alphabetical order and enclosed within a circle. This clear demarcation helped collectors easily identify the production year.

1997–2014: The Square Era

From 1997 onward, the date letters were enclosed in a square, a design that continued until 2014. This change was subtle but significant, aiding in quick visual identification.

2015–Present: Return to the Open Letter

Since 2015, Hermès has reverted to the original open-letter format, with letters progressing from 'T' (2015) to 'K' (2025). This modern approach maintains the classic aesthetic while ensuring clarity for future generations.

Special Stamps and Their Significance

Beyond the date, Hermès uses distinctive stamps to denote exceptional pieces. These marks differentiate a standard retail bag from those created under unique circumstances.

The 'S' Stamp

An 'S' stamped on a bag indicates it was sold at a discounted price, often from a sample sale or as a second. Such pieces are typically not eligible for resale at full retail value and carry a unique provenance.

The Horseshoe Stamp

A horseshoe mark signifies that the bag was a special order, crafted to the exact specifications of a client. These bespoke creations are highly coveted and often feature unique colors, leathers, or hardware combinations.

The Shooting Star Stamp

The shooting star is a rare and coveted mark. It indicates that the bag was made for a Hermès craftsman or employee, and as such, it cannot be resold. These pieces are considered the ultimate insider treasures.

Material Stamps for Exotic Leathers

Hermès also employs symbols to indicate the type of exotic leather used, which is crucial for authentication and valuation. Each mark corresponds to a specific species and origin.

Porosus crocodile: Represented by a short dash or a specific symbol, indicating the highest grade of crocodile leather from Australia or Southeast Asia.
Crocodile niloticus: Marked with a different symbol, this leather comes from African Nile crocodiles and is prized for its scale pattern.
Alligator: A distinct stamp denotes American alligator, which has a finer grain and is often used for more casual styles.
Lizard: A separate symbol is used for lizard skin, a lighter and more delicate exotic option.
