Hi. Take for instance these items that I know for sure are FAKE Coach bags. I will include explanations below the links. Please refer to some or all of the bags' pictures if you wish.

(6 of which are from the same seller--> Member id: thatoldthing2 <--BUYER BEWARE!)

5) http://cgi.ebay.com/BEAUTIFUL-LARGE-COACH-LEATHER-PURSE-HAND-BAG-A2J-6094-/180547179529?pt=US_CSA_WH_Handbags

--crooked hangtag, signature lining when not supposed to, C's wrongly symmetrical, serial # with "6094" is a Demi style bag (much smaller than this!)

6) http://cgi.ebay.com/UNIQUE-SLIGHTLY-USED-COACH-PURSE-HAND-BAG-NO-10004-/180547151920?pt=US_CSA_WH_Handbags

7) http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=320575900641&ssPageNam e=STRK:MEWAX:IT

--signature lining, NO serial number whatsoever on creed

8) http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=320575944137&ssPageNam e=STRK:MEWAX:IT

--no symmetry on C's, signature lining on an ALREADY signature bag!

9) http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=170528338925&ssPageNam e=STRK:MEWAX:IT

--what the freak of a creed patch is that?, hangtag is supposed to be leather NOT clear (taken from a Poppy bag I see)

10) http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=260650951648&ssPageNam e=STRK:MEWAX:IT

--C's not centered down the seam at all (looks weird on first pic), No "Coach" engraved on a Carly bag EVER, cheap shiny leather and cheap stitching, lining on a Carly is always supposed to be plain and cotton not striped (only occurs on plain leather bags)

So, the rule of thumb is Coach bags that have C's on the outside always have to have plain lining on the inside, C's are mostly symmetrical down the center (except for Optic and Scribble patterns) and if there's a creed patch, it has to have valid serial numbers that can easily be found/matched with another bag anywhere online.

**I am not here to make fun of these bags...I am just here to get your opinion of whether you agree that all these bags are fake or not. My main purpose is to NOT get any eBay buyer scammed by these sellers especially since many of them might think they're getting the real deal when they're not...unless of course they are aware they're fake or they're buying bags from flea market that they know are mostly likely fake Coaches. That's all.
Here are two more bags:

11) http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=160466418332&ssPageNam e=STRK:MEWAX:IT

--not specifically symmetrical down the center because the C's on each ends are of different thickness (so to speak)

12) http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=270623025573&ssPageNam e=STRK:MEWAX:IT

--metal hangtag (supposed to be golden brass or shiny nickel not gray), creed patch that has NO serial number anywhere and signature lining on a Sabrina? I don't think so (either shiny satin or cotton).
