Help Identifying Mint and Moneyer of a Henry I Double Inscription Penny.

[JN13]

Hi, I recently bought a rare Henry I Double Inscription Type Penny, which I am very happy with, but I have been unable to identify the mint and moneyer of the coin. I think I can make out 'PA...N...ATR' on the reverse, but I am not sure. I have uploaded a photo of the reverse of the coin, so any help anyone can give would be much appreciated.

Thanks

Hi is it possible to see the obverse ...

Here is a photo of the obverse, the portrait has some double striking but it is clear enough to see the main details:

If it is as you say, the obvious candidate would be Gilpatrick at Pembroke, the mint being written, PAN  or PAIN. Have you tried searching the EMC database at the Fitzwilliam? If it was found by a detectorist it should be recorded with the PAS and the details will be uploaded to the corpus. An auction would not necessarily be recorded there unless found under the treasure rules. Where did you get it?
