Information Needed for Authentication With both the forums and the business websites, it's important to follow a few general rules if you want to authenticate your bag. So watch out using the number only! In fact, you can roughly determine the decade during which a particular Vintage Coach® bag was manufactured by observing particular characteristics of its creed and serial number.

I have emailed Jennifer to let her know and I am posting the history of Coach creeds and serial 's, for any person who is interested in older Coach bags and vintage Coach bags manufactured before the 1990s.

The all-number xxxx-xxx serial number format began some time around 1989 and continued thru late 1991 or maybe early 1992, again verified by cross-checking bags with that format of serial number against their production dates as given in Coach's catalogs.
