If you think CNG has even considered that they might need, in this day and age, to soothe buyers' concerns with any kind of collecting history for this coin of Zenobia, ruler of Palmyra, you'd be overestimating the sellers and buyers of dugup antiquities:
Despite the patronising and evasive description, some coiney has such a desire to get his hands on it, that he's currently bidding: $11777. And yes, I bet it is a he.
And yes before any smarmy coiney triumphantly announces that "Barford did not notice it was minted in Antioch and he does not know Antioch is not in Syria" - he did and he does. The coins still should not be being offered without a collecting history.
