It isn't a vintage bag. It was made for factory in 2007. The E stands for the fifth month - May, the 07 is the year, the 51 is the factory code. The F before the style number means made for factory. The style number is 9790. They just added the 0 to make it consistent with the length of current style numbers. It is authentic. It may have a different feel than vintage bags.I recently purchased this Coach City Bag in butter soft glove tanned leather, it was at my local SA store...but I have some doubts if this bag is authentic.I never saw the creed numbers looking like this.I am just starting collecting Classic Coach bags and can you, please , explain to me what do they mean!As far as this bag is not selling on Ebay but is in my private possession, I cannot provide seller ID and auction #.Just want to be sure if this bag is authentic.Thanks a lot in advance!
