9.6 Gramm (UK?) Copper Coin. [gelöst]

Hi guys, I need some help to identify a coin.

It's a round Copper coin with no readable legends or dates.
The person on the Obverse of the coin facing to the right and has a little tail of hair bottom left (like, for example on the Charles II 1/2 Penny coins) but both side of the coin is very loomy, hard to see any details, but I'm just very curious. :-)
It's weighing 9.6 grams and approximately 27-28 mm in diameter.

Any idea, what is this coin?
Thanks.

That size is a 1/2 Penny.
May be one of these ...

Thank you very-very much!
It's the second one: ½ Penny - George III - 1st issue.
Kind regards.
Gabe.
