Hermès Blind Stamps: The Signs of Greatness

Hermès Blind Stamps

With a lineup of bags that has earned Holy Grail status in the world of accessories, Hermès is one of the most recognizable brands in the world, yet there are many small signifiers on each of its creations that people wouldn’t recognize. These are the markers that indicate the year, skin, and even the craftsperson who put your treasure together. One example? Crocodile bags are identified by two dots stamped next to the logo, alligator by a square, and lizard by a double hyphen. As a collector, I’ve come to recognize various features, but even the most dedicated aficionado can learn more through research. In this post, I’ll be sharing my findings with you, starting with the blind stamps that identify the year a bag is made…

How to Read the Hermès Blind Stamp:
The letter “A” inside of a square denotes a bag from 1997, the first year that letters were encased in squares instead of in circles. My vintage Kelly bag has a “B” stamped in a circle, and it’s from 1972. Birkin and Kelly Bags made after 2015 are stamped on the side interior gusset.

Years 1997-2015: Stamped with letters inside of squares

Years 1971-1996: Stamped with letters inside of circles

Years 1945-1970: Stamped with a letter corresponding to the year

Hermès Sizing for the More Popular Bags:
Kelly bag: 15cm and 20cm are very rare and have been discontinued since the ’90s. The new Kelly Mini II 20cm was reintroduced in 2017. Custom orders are on a case-to-case basis. More common are 25cm/28cm/32cm/35cm/40cm.
Birkin bag: As with the Kelly, birkins sized 15cm and 20cm are very rare and have been discontinued since the ’90s. More common are 25cm/30cm/35cm/40cm/50cm.
Constance bag: 10cm/18cm/23cm
Evelyne bag: 18cm, 29cm, 33cm (TPM/PM/GM/TGM)

Fun Facts:
Hermès’ signature orange boxes and bags have come to be associated with the highest form of luxury, but the color was initially chosen for its inexpensive price. Post-WWII, no one wanted the hue for their bags, thinking customers would prefer other colors like black, so there was an abundance of orange dye.

The Sac à dépêches was a saddle holder. After a few changes in design, it was renamed the Kelly bag, as Grace Kelly had popularized it while using the now-beloved style to hide her growing baby bump from the paparazzi.

The HAC (Haut a Courroies) is the original iteration of what we today know as the Birkin. In my opinion, this is highly collectible. Created in 1892 as a horse feeder bag, it was updated in the ’80s and customized for Jane Birkin’s jet set needs after Hermès chief executive Jean-Louis Dumas saw her fumbling to fit her straw bag in the overhead compartment on a flight from Paris to London. They customized the Birkin to be wider and shorter than its predecessor. This year, Birkin requested her name be removed from the crocodile version of the bags due to allegations of abusive practices in obtaining the skins.

Hermès uses the most expensive alligator (American alligator mississippiensis) in the world, the skins don’t have small holes on the scales, as you see with less expensive alternatives. This is slightly more costly than crocodile skin, of which the company prefers the niloticus and porosus species (they don’t fool with Caiman croc or any lesser crocodiles).

A square stamp next to the logo denotes alligator skin. This is a matte malachite alligator; see how perfect its scales are without a single pinhole? It’s truly perfection.

Rose Tyrien shiny, porous crocodile. Hermès uses an agate stone to polish its crocodile and alligator skins to a shine. They don’t glaze their skins as other brands do, so your bag won’t peel or crack as easily. With use, the shine will dull, creating a nice patina.

You can order canvas straps (Bandouliere Supplement) for your Kelly bags. It’s a sportier look and can transform an exotic like my white ostrich into a casual bag. I mix and match my straps. It’s so much more fun!Hermès Blind Stamps

        My bag is marked with a square around the letter C I think and to the left of the opening a 41S. I’m not sure how to measure but I think it is 34 cm or so. Please help. Do I measure height or width?

        • August 27, 2018 / 11:15 pm

          Hi there, it’s most likely a 35cm. Size is indicated by the width of the widest part of the bag! x Tina

    I love this info, but I just recently came across a Kelly bag, and would like to know if it is authentic. Do any of the Kelly bags have material lining on the
    inside with Hermes Paris on it ? I can’t seem to find any stamps on it, and it has gold coverings on back and front of the straps that closes the bag, from
    other pictures I’ve seen the gold coverings are only on the front and the back of it is where the stamp should be, can you help me with this.
    Thank you !

    Have you ever come across a blind stamp that is sideways? As in, the letter A is in a square (so dated 1997) but it’s on its side and not the usual straight on behind the sangle/strap? To be honest I’ve only seen it straight. I’m currently looking at a vintage kelly but because of the alignment of that stamp I’m iffy about buying it. Please help. Thank you!

    • June 22, 2018 / 8:28 pm

    Hi! I recently purchased an Hermes Birkin. It is a 2007 (K in a square), 25S. It passes every test of authenticity, except it came with an card of authenticity. It came with an orange duster for both lock and key and bag. Does that card really automatically rule it out as a fake? I found at a thrift store (I’ve purchased Milly and DVF there for $2- they dont care what stuff actually sells for as they are a non profit, religious organization). I am grasping at straws at this point but am hoping someone maybe had 2, a real and fake and accidentally donated the card with the real? HELP!

    I bought a Vintage black croc Kelly at a sale of designer clothes and bags which had belonged to a well known local lady who had died. It comes with gold hardware, with Hermes-Paris and a hallmark, no Hermes Paris gold stamp. The odd thing is it has 5 feet. I don’t know much about early bags but I guess it must be a v nice fake but i’d love to be sure

    Looks like I have Hermes Kelly bag from 1948 from my 83 years grand mother but there is no : made in Italy under Hermes Paris on the front stamp. Is it common on early bags they did not print where it was made.
