How to authenticate a Chanel flap bag: The complete guide

Having worked in the preloved designer resale business for over 10 years now I'm sure you can imagine I have seen a fair few beautiful Chanel flap bags. I have also seen a fair few super fakes and they are getting worryingly close to the original. In Entrupy's "state of the fake" report, they conclude that Chanel was the third most faked designer bag after Louis Vuitton and Gucci in 2018.
The following tips should give you some peace of mind when looking to buy, or if you're looking to sell you can get in touch with us to arrange an authenticity check or to learn more about selling your Chanel bag with us. 


At this point, just to get it out the way, I am going to address why, even if the copies are fantastic, you should hold out for an authentic piece and my short answer is: that it's important to invest in goods that not only have value but also integrity. Goods that are produced by people that are working in inhumane environments and whose funds do not contribute to the black market. If you're interested in this you may wish to read the article 'Fake designer goods fund black market' by the BBC.
Just last week I sat two Chanel flap bags side by side to compare and could barely spot the difference between the authentic Chanel bag and the fake one. Further to this, it is also common for natural differences to occur due to the fact that luxury designer bags are often hand finished or have different finishes due to their year of manufacturer. This can often cause people to be anxious that the bags are fake when in fact they are authentic



So how can we get around this? Below and in the video above I give my top tips for authenticating at home, but I have to say that the best thing to hit the second-hand market in recent years and something I hope will combat super fakes is in fact EntrupyEntrupy is a mechanism that uses machine learning algorithms on microscopic images of physical objects to distinguish between genuine and counterfeit versions of designer goods. It has a 99.1% accuracy rate and has been used since 2012. Whilst Sign of the Times offers designer handbag authentication in London via Entrupy, I realise you may also want to do your own authentication at home so here are my top tips.
 

1. Serial number



Head straight for the serial number. Authentic Chanel handbags from the mid-1980s onwards would have been produced with an authenticity card embossed with a serial number which matches the serial number that appears in a sticker found somewhere within the handbag’s interior lining.
The Chanel logo, hologram design and sticker will vary according to the year they were manufactured. A note here it is crucial that you keep this card for maintaining the value of your bag. The serial number can be traced by Chanel to detail what the bag is and when and where it was bought so it is key to proving authenticity and pretty hard to copy. Beyond just “having a serial number” each hologram has its own personality. For example, some numbers are serifs, some zeros have strikethrough etc. I have a full list of what to look out for below. This is written in 2019 please note that the current codes are 27 series. It is hard to copy the exactly speckling, or transfer these holograms due to the slice throughs. Having said all that on some of the earlier models the authenticity sticker was literally just a sticker and could have rubbed off over the years.

2. Hardware

Photo attributable to Vanna Garcia

The writing and embossing of the Chanel Paris on the hardware at the back - it is hard for them to get an exact match - sometimes it’s just about having seen lots of them to know if something looks off at the back but often the fakes have the words embossed to heavily. 


3. Gold Hardware myths



This first thing I want to do here is to clear up some false information I have seen circulating about the "Chanel made in France" on gold hardware brands. I have seen it said that this cannot be under the CC logo inside the flap if the bag has gold hardware and is made in France. In short this is false and it can - I have seen authentic bags that have gold foil in this position under the logo. 
The Chanel locks - The original CC lock can feature either flat or raised finishes with the right C overlapping the left C at the top and the left C overlapping the right C at the bottom. Sometimes in the gold hardware you will see. Hallmarking - there is also a lot of controversial information out there about the hallmarking on gold CC bags.
 Before mid-to-late 2008, you can see a small stamp on the top left, top right, or the bottom right of the CC logo turn lock. The location may vary based on year and where the clasp was created. However, some Chanel bags with gold CC turn locks were not hallmarked at all; for example, if they have a matte gold finish or if they were made in Italy, they may have no stamp.There will be no such markings on the silver hardware.
 
3. The screws 
Chanel only use two types of screws: Hex and the flat screws. You can see an example of the flat screws in the photo two photos above. The hex screws above on the left are authentic and on the right fake. 
The popper button which secures the flap should have "Chanel" embossed as well as the location of manufacture. 


4. The chain



Both the chain and hardware can tarnish on a real bag - so if there is some tarnishing do not let this put you off. Another interesting point is that the length of the chain (the drop) on a medium flap bag means that it hits you just lower than your ribs when the bag is worn across the body. You can see this demonstrated in my video above. However please note you can have extra links put in so if you’ve bought it preowned this could account for why the chain is slightly longer.  Beyond the length of the chain it is woven with leather which is triple folded down often the fakes will only have a double fold and this will be machine stitched.

 
5. Internal zipper

Chanel zipper authentication

The options for the internal zipper are different depending on the age of the bag and you can use the serial number to determine the age and check that this is consistent. The following information was found on Vintage United: from the early 70's Chanel was using zippers manufactured by Lampo, is an Italian company that has been making accessory zips since 1887. You can find Lampo zips not only on vintage Chanel bags but also on vintage brands such as Louis Vuitton. Another company that is synonymous with luxury brands are Eclair zips. Often Eclair zips are used on late 70's or early 80's vintage Chanel bags and also on vintage Hermes bags. Later in the 90's House of Chanel also use other zipper brands like YKK or DMC or OPTI DMC. You can find this logo stamps engraved on the main zipper pull. In the "modern" exemplars Chanel using a zippers from the company with EP logo stamp. The EP zipper pull usually have a thin leather pull tab, please note that the leather pull tab should match the main bag base. 
You can use the information that you gleaned from your serial number to determine what year your bag was manufactured and therefore what type of zipper your bag should come with. 


6. The leather

Chanel quilting fake

If you have a look in my video you can see that whilst there is some "puffyness" to the quilting it does not have a pillowy effect. Often you will find on the fake Chanel bags the quilting is a bit puffier due to a lower stitch count. For an authentic Chanel bag you want to be looking for about 10 stitches / inch. Below you can see an image of fake Chanel stitching and leather. It is a costly process as the needles have to go through a lot of times. The stitch lines will also match up perfectly on the back over the back pocket. 
Beyond the external leather - interestingly you will find that the lining on an authentic bag is easy to pull out.


 7. The only step needed

Chanel Authentication London Entrupy

The steps above will most certainly get you out of the woods when dealing with "regular fake bags". The bad quality ones that you can pick up for £50 or so. However the rise of the "super fake" is causing authentication by eye to become increasingly difficult. Even sat side by side it can sometimes be near on impossible to tell the difference. As Chanel continue to increase their prices (the current price of a medium flap bag is £4300 in August 2019) the market for people paying in the region of £300 for a super fake is growing. 
Therefore to date I have yet to come across anything better than Entrupy for telling unequivocally if a bag is genuine or not. Entrupy goes beyond just what the human eye can see, touch and feel and actually use technology to investigate at the microscopic level. We currently use this at Sign of the Times and would be delighted to use it to authenticate your bags for you. You can bring your items to us for authentication at our store in Chelsea, London. Alternatively you can post them to us. Either way please do contact us to organise. 
Entrupy works by taking microscopic pictures of the leather to see if there are any plastic particles or inconsistencies to an authentic piece. It is over 99% accurate and works using artificial intelligence to keep learning.
