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.

        Hi I know this is an old article but I recently found a Hermes bag in a charity shop and wondered if it was real.

        Is there any way I could send you photos? It has an actual Hermes logo on the front of the bag which looking online none seem to have?

        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 really enjoyed your thoughtful and insightful article. I have a Black Crocodile Kelly Bag with stamps that I do not understand. They are: S in a circle followed by R…then in the other side there are either 16 or L6.

      I am selling my bag and the buyer quite rightly needs to know this before purchase. Since the bag has always been in my family and rarely used but sent to Hermes to be conditioned, both to Her es, Paris and to Hermes, NYC (Mr. Claude worked on this bag until he retired).

      Any information would be GREATLY appreciated.

      Best wishes,

    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!

    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.

  26. Bridget
    September 23, 2019 / 4:47 pm

    The little holes you refer to on Crocodile skins are sensory ‘pits’. All Crocodiles, Alligators and Caimans have them. The difference is that Alligators and Caimans have them only on scales around their jaws and Crocodiles have them on scales over most of their bodies. It is one way of telling Crocodile skin from Alligator skin. Their purpose is unclear but probably to do with pressure sensing and in Crocodiles possibly for salinity detection as Crocodiles live in salt water and Alligators principally in fresh water. Generally speaking Crocodile skin is more expensive than Alligator and usually considered to be more desirable. However, there are considerable ethical issues around purchasing new items made from exotic skins and personally I would not do so.

    Hello, with all the information posted here you would think it would be enough to know if I have been left a authentic Hermes Clutch but alas I a still unsure. Can you please help me to find out if I have an authentic or a fake because it is a very cute bag but I cannot see one similar anywhere. This particular Clutch has the letter A in a circle and its on the round stud (the kind that is magnatised). Also on that stud and the other smaller one are numbers (very hard to read). The bag has 8 gorgeous colors with the main color Orange on the back and the front consists of Tan , Teal, Pink, Red and Yellow. Is there a way I could send you a photo please? Any information would be most appreciated. Warm regards,

    Any ideas on where to find the date on a diamond birkin? My mother has one and wants to sell it but cannot remember when she got it over the years as she almost basically carried it. There are six digit codes on the back of the plaques (073675) but a different six-digit code on the lock (072630). All three have the same three-digit code additionally (750). I looked inside to find an alternative place for the year. Ideas? It’s a 30 cm black croc.
