Hammered Sceatt? Anglo-Saxon? Celtic?

[statmatics]

A metal detectorist uncovered this 15 mm diameter   coin in Cumbria (North West England) and sent these pictures for identification.

Whew! I have looked through a bunch of reference material, but nothing has appeared.

If you can help, please do! --- Thanks!

The upper picture could be inspired by a Hellenistic or Roman type head, but the monogram doesn't make any sense for such a coin.

The monogram of Zenonis comes close. But I have been unable to find a match.

I very much doubt this is genuine somehow,
it looks very similar to objects being sold as metal detecting finds on ebay in recent years.
The seller probably appears here;
