What is exactly would this style be called. None of eBay categories seem to work. Appears to be a sort of single strap over the shoulder bag. Tempted to call it “backpack” style but not sure if that’s correct.
The last four digits of the handbag indicate the style. I did a search and it doesn’t look like your bag. Either it is very old or not legit. It doesn’t look impressive for a Coach (which isn’t that expensive in terms of fancy bags anyway) but it’s up to you.
I can sell you mine if you really need one. innocent look
Checked with Coach purse authentication site and uploaded pics. Turns out it is a genuine 1997 Coach bag (and apparently somewhat rare) called the 'Flatiron Sling"!
