If it's for details like a dot below the I, then you can understand why TPGC's don't release their findings to the general public! Especially when you consider they may have this information whilst the dies are still active. One would presume, with the TPGC's financial investment in not slabbing a fake, that the last thing they'd be doing is saying 'hey me old China, you need to do something with that little hole in the field of yer obverse die, or you'll not be selling any more forty-niners!' Great work so far Rob and Seuk, been burning some midnight oil I see!
