Both bags are very common styles with several different versions and style numbers. Even if you don't specifically ask to have them authenticated, we still need to see the creeds and serials, and we would definitely need to see them to identify the bags. If you're going to be selling them you'll need to post those photos in the listings anyway so you may as well have them available.
Remember, if a bag ISN'T genuine, then as far as we're concerned it has NO identity other than "fake". If they turn out to be fake, selling them anywhere in the US is illegal, and selling them on Ebay can put your selling privileges at risk, so any time you sell a highly-faked brand or item for someone else as a favor, it should
ALWAYS be authenticated. We have a special thread that should be used for all authentication requests over in the Coach Shopping Forum. The only time you can be sure a highly-faked brand is genuine is if you bought it yourself right from the manufacturer's retail store (and even then a few fakes per year can slip through).
Don't try to post photos larger than about 1200x900 pixels Even though larger sizes are supposedly allowed, the forum software will limit how many pictures you can post if the first ones are too big. Creed photos should be right around that size or at least 800 pixels wide (100 pixels in most computer screen resolutions is roughly one inch or 2.5cm) since we need to actually be able to read them and look at the details to be sure it's authentic.
If you're using a "real" computer, try a program called Irfanview for a simple way to reduce the size of photos (as well as dozens of other tricks). It's spyware-free, lightweight, easy and it's free. I've used it for ages. Hope posting the link is ok:
