I've checked some of my old Coach catalogs and the closest I could find was back in 1999. It looks like it's part of the Coach Neo collection. I couldn't find your specific bag, however there is a Coach Neo Lunch Tote, Style Number 6201 that is very similar. The lunch tote does not have an outside pocket like yours does. Also, I used the drill down to search for 6201 and got nothing.
Hope that helps a little.
