The story is becoming complicated and I can't say I have the details in my head clearly. But the main question at present seems to be, was the Mark fragment ever for sale, and if so, by whom? Dr. Nongbri has another questions about the other fragments:
So, now a question for the people associated with the Green Collection and the Museum of the Bible: Do we have any provenance information on these pieces? They have a similar character to the Oxyrhynchus Mark fragment, and they seem to have become a part of the Green Collection at about the same time as the Oxyrhynchus Mark fragment was alleged to have been for sale. It would be most illuminating if the Green Collection or the Museum of the Bible would provide detailed acquisition information about these pieces.Background on the Mark fragment is here and links. A post on the announcement about the Romans fragment is here. And a related post on supposedly early New Testament fragments is here.
