I wouldn't know what to gin it at, but there's no holes, stains, or anything of that nature. Oh, and yes, it's authentic :-) I hope this helps and fanning back!
Can you validate what the spot is in the photo of the purse backside. Between the first full C's on bottom left. It looks like a dark ink blotch. Is this just a photo shadow or is there a stain in that spot?
