I could be wrong but I 'think' that one was made specifically for the outlets (the one that does not show up in the drilldown) and the other was for the boutiques and online. I'd call Coach, give them both numbers and ask what the difference is. I remember quite a while back that someone said the outlet leather wasn't as nice as the boutique leather. Again, don't know if that's true, just what I remember!
I own this bag and bought it from the Coach outlet store. I just checked my bag and the number is 10205. However, my bag is leather and the description on ebay says that the bag is canvas and corduroy. This was not made in canvas. Just for a heads up, I paid $90 for this bag in April at the Seattle outlets.
