There are many signs, noted marks on handbags that a seller should show pictures of, describe or have guaranteed for a handbag.  If a handbag is 100% Authentic, it should always be guaranteed or your full money back so that you have that satisfaction of knowing that your handbag is indeed 100% Authentic.  There are many marks on a Coach, Louis Vuitton & Gucci handbag that will show it's authenticity. 

On all Coach, Louis Vuitton & Gucci handbags there are many key important factors that all of these handbags have.  There is always a leather tag inside of the bag that has a ID number.  If your handbag doesn't have a tag with an id, your handbag is most likely fake.  This ID tag is marked as a real bag from one of the designers. 

Secondly, all 3 of these trademarked handbags (Coach, Louis Vuitton, & Gucci) usually do not come with plastic wrapped around the handles and/or handbag.  That is usually red flag and indicator that it was imported from China or a foreign country and is a replica handbag. 

Thirdly, feel your handbag, you will know leather from fake leather.  If you question the texture, take it to a shoe shop or any designer store.  They will be more then happy to help you out and access the quality of your handbag.  Last but not least, is your handbag purchased from someone with a good feedback rating?  If they most likely have any negative feedbacks, this also is a red flag they are possibly selling knockoffs.  If they are selling the handbag and it is out of a boutique or from China, this is yet another red flag it is a knockoff. 

If your Gucci or Louis Vuitton handbag comes with tags hanging from the handle this is also an indicator it is a knockoff.  A 100% confident seller will show the proof of payment from the designer store or have a 100% guarantee for when you purchase.
