RE:
53bigbooka
I think you have the incorrect item number and link for 53bigbooka's listing.
I think this is what you're looking at:
Item 121174802868
http://www.ebay.com/itm/Vintage-Coa...868?pt=US_CSA_WH_Handbags&hash=item1c3694c1b4
My comment concerns the seller,
53bigbooka. Although the listing you're asking about might be okay, it's worth noting that the seller had listings for several fake
Coach bags in early
January. All had invalid serial numbers.
Then in
February, the seller had another fake Coach bag, again with an invalid serial number.
And in
April, another fake bag was listed and ultimately removed.
A seller who sells as many Coach bags as
53bigbooka should be authenticating them, or at least learning about how to read and understand serial numbers.
This is the creed from one of the (at least 6) fakes listed and removed. (And sadly, this bag had been deemed authentic by Carol Diva.

station85 (on Etsy) is station_85 on ebay:
This seller's feedback shows she has a history of not accurately disclosing the condition of the items she sells.

I wouldn't buy from either seller.
