I recommend going to Sear, as Ron suggests. I edited this post since NGC now has a different statement on their site, as compared with the older quote I had posted. But the gist is the same. Among their current statements is "Authenticity and attribution...are not guaranteed, nor is any guarantee implied." Of course they won't slab a coin they think is fake.
Sear is not infallible, but his opinion has weight - or should - with serious ancients collectors, IMO.
