I dimly recall another documentary about fake antiquities, biblical in nature, coming out of the same area as the box did in your Wikipedia link. I seem to recall that there was some investigation into a master forger who was pushing works out through unsuspecting dealers? One item was a box (I'm not sure if that's the same one) but there were more of them that were being questioned. I think the conclusion was that they did not really know but there were some pretty big indicators that they *might* have been forged. I think, in the documentary, someone went to prison for a long time (they take this stuff serious it seems) but it was for different charges?
I really should start trying to remember the names of all these documentaries. *sighs* The thing is that I watch them for light learning and amusement and not as a rigorous study or anything so I tend to forget all the names, details, etc... It probably doesn't help that I used to drink a great deal and watched many of them while I was drunk.
Thanks for the links. I may return with more questions - I'm off to read the first two links.
