1) even though the code has been damaged slightly, there are a few key authenticity signals. The 0 has a line through it (fakes don't have this line), you can clearly tell by the size of the sticker that this was a 7-digit code which corresponds to the early 2000s era. lastly, the last 4 digits are clear - 2890. This sequence doesn't match any commonly faked chanel code.
2) the stitching and hardware is amazing on this bag. super crisp and clean engraving everywhere. Most fakes have very rough or messy stitching and hardware. The turnlock works perfectly and the chanel zip pull inside is perfect.
As always I recommend everyone to do their own authenticity check but this looks real to me. Please don't lowball on this. This is the best bag I've sourced so far, so cannot let it go cheap.
One minor stain, pictures in the last photo. barely visible when wearing.
