You are right. I highly recomend Sadigh Gallery. Following your advice I have ordered:
A panel http://www.sadighgallery.com/Panels_p_37457.html
A pendant http://www.sadighgallery.com/Pendants_p_34737.html
A manneken pis http://www.sadighgallery.com/Statues_p_38077.html
A victory of Samothrace.
Well, not one ,quite a few for a miserly 134.700 USD.
The "panel" is incredible. I can hardly think of anything that looks less ancient.
As with many such dealers the expensive
fakes may be
salted among cheaper genuine stuff. More or less the same as hiding the
Didius Julianus among the Constantines. So when an
LRB collector says "I bought some Constantines and they seem authentic" that helps in no way to authenticate the
Didius Julianus. Of course anyone is free to purchase from an
antiquity dealer and then imagine/believe the items to be genuine. I would not like to intrude on areas of personal belief. I'm after all a priest of the cult of Mithras so am hardly in a place to comment on the strange beliefs of others.
Seriously though, the rules of the scientific method apply to sellers of
fake goods - negative results (apparent fakery) over-ride any number of uncertain results (possibly ok purchases). It is not very relevant that some people have bought apparently genuine items. That's the "I bought some
LRBs" defense. It is that others have been sold
fakes, and because of this pattern, the next person may be sold a
fake. Perhaps Chris buys in areas that he is an expert in, or that
Sadigh has not learnt to
fake yet, or that other authenticators are not expert in, but that doesn't change the message shared by many people over years.
