Help identifying Celtic (?) coin please

[Paddy]

Can anyone point me in the right direction for this coin? Came to me as "unidentified Celtic". Looking through Spink and Mack the closest I can get is Regni uninscribed, but not an exact match.

It appears to be Copper, measures about 11mm across and weighs 1.89g.

Thanks!

I had forgotten about this query as I got answers on another forum. It is, sadly, a fake and apparently there are lots in a similar style on Ebay at present. I returned it to the auction house for a full refund.

What is supposed to be?  Potin of some kind? Eppilus? I can't identify them for toffee.

I don't believe it actually copies any specific Celtic coin, it is just done in that style, which just adds to the difficulty in calling it out as a fake.
