First off, diesels are shipped overseas in bags, but these bags are LONG, large enough to fit the jeans folded in HALF. If the bag you got will only fit the jeans when they're folded into four, that's not good. The little R symbol on the coin pocket has no bearing on authenticity - different countries have different copyright laws so depending on where the jeans were made to sell they may or may not have that R. All the european ones dont whereas all the US ones do, for instance. All zathan 772s that I've seen DO have microstitching, so generally that is a good indicator of a fake if its missing. The head tag DOES have numbers stitched into it, but depending on how the tag is sewn into the jeans, you may or may not be able to see it, eg:



As far as the color & wash etc, there IS a lot of variation in diesel jeans. It would be easiest for us to see pix of the jeans or, if the listing pix are accurate, a link to the listing. Preferably both

The 'data' thing on the tag does in fact state the date of manufacture but even the fakes have this so that alone is not a proof of authenticity or not. Finally, as far as your cherones, some of the tags say LAV and some say ART instead. But all of the 772s are new enough so they should have ONE or the OTHER on the inner tags.

Post links to the auctions and/or photos of the jeans so we can render a final verdict!
