ALIN SUCIU notes an upcoming auction of Coptic manuscripts: Christie’s Auction of an Early Christian Papyrus Document. They include fragments of 1 Kingdoms/1 Samuel and of a psalmic work that may be a biblical apocryphon and which may or may not be Manichean (Manichaean). Both manuscripts have been published previously.
As always, the ideal would be for a philanthropist to buy the manuscripts and donate them to a museum. But if that is too much to hope for, I do encourage any buyer to make the manuscripts available for scholars like Alin to study.
