!- The serial number probably starts with 618- , it can't be 61B, newer numbers from 1994 or later that include the style number always have to start with a letter. So it's not made in 2001 either. It's one of the Drawstring Sacs from around 1987, probably the Small if it's about 8.5 inches high. The Made in USA stamp is unusual and has shown up on fakes but also on some apparently genuine bags too.
2- It SEEMS ok, but M is one of the plant codes that turn up with different countries' creeds so it's hard to be 100 percent sure. I'd call it "probably genuine." Sometimes (a LOT of times!) it's impossible to be really sure because no one knows how often
Coach broke its own rules about those plant codes or how often an item stamped for one country would actually have been made in another and the item stamped Made in The US. With Coach beating their chests so much about being an American company promoting American style, I'm sure they got a lot of criticism when they started manufacturing outside the US. This may have been one way to silence their critics. But no one who was there knows, and if they know, they ain't talking, at least not to me.
3- M is the standard code for December - my posts explain that the letter "i" as a month code was
usually skipped. AGAIN, there are exceptions. It's a genuine Sonoma Drawstring.
4- Legacy Crescent, 2001. Sometimes that hyphen shows up, it's only a red flag when there's a second one actually in the number itself. The "No" isn't considered part of the serial number.
5- Don't be so concerned with where the Made In is stamped as long as it's not on the bottom in 1996 or later. Like I said, it was changed gradually over 2 years. There are almost NO cut-and-dried Rules about creed stampings. Keep repeating this until it's engraved on your brain - "the most consistent thing about Coach is its inconsistency". As for the pocket, I have NO idea where it's supposed to be. When you find something like that, the best thing is to use Ebay's Advanced Search, specify Search Titles and Descriptions, and see if you can find more like it.
