do a search for "gucci horsebit" and you will find a slew of fakes, some of which look good. the giveaways are the cheesy gucci paper tag and the round raised thing above the zipper pocket that might be a magnetic closure (in the picture where she's lifting the serial number tag) -- the real one does not have any sort of closure. and $425 for a very popular bag (the entire country was recently sold out) that retails for $1200?? I don't think so. and I'll bet the starting price was really low and there was no reserve -- who in their right mind would do that??! private feedback is also a tip-off. did your friend ask her if it's authentic? it's always better to have it right from the seller's mouth. have your friend take it to a Gucci boutique if she wants to know for sure (or not, if she loves it and doesn't care). or it looks like she can return it (allegedly) if she contacts the seller within 24 hours.
