I guess that could be an asking price an for old pair with cosmetic problems - for example new frets aren't cheap (the regular black frets are about 200 euros a pair, I just asked). They might also have blown tweeters, or something...
I don't think there are fakes, but it could of course be a scam of some other kind, especially if the seller claims that they are newish and in excellent condition. Most people would have the sense to find out what a new pair costs!
But if they are local, perhaps you should just go and take a look (and make sure that they work).
