I don't see any problem with the bag.
However, please be aware that this is considered a POUCH, not a handbag! It's very small, maybe only about 9 inches by 5 or six, and the strap is also short and may not fit comfortably on many womens' shoulders, especially now that it's winter and many of us are wearing heavier clothes and coats. The strap drop is probably only 6 or 7 inches at the most.
BTW, cards that supposedly come with
Coach items don't prove a thing about authenticity - any crooked fakes manufacturer can print or buy fake cards and price tags and almost all of them do.
The seller doesn't give any measurements in the listing, which to me is deceptive when it's a small accessory bag that's being sold. Pouches, Demis, Swingpacks and other small bags are considered Accessories by Coach and they may or may NOT have creeds or serial numbers.
