Help with Identification [Resolvido]

hi all, is there anybody who could help identify this coin. It came out of a bag of pre decimal coins. It's approximately 27mm in diameter and 1mm thick.

Apologies for the quality of the photos!!

Maybe either of these ...

as the hair nearly touches the edge on top left -
and on other side may be Britannia with an exergue below.
Maybe.

Once cropped and brightened, in that second picture I can almost see the letter S on
top left also - which is also what is on the coins in those two links.
Here are my two amended pictures, and an animation with the coin in the second link ...

So as you are in UK and it was found in a bag of (presumably UK) pre-decimal coins,
and the size is close (normal coins are 28mm and your worn coin is 27mm),
it looks likely to be a 1/2 Penny from around 1729 to 1754 dates.
Maybe.

Brilliant. Many thanks guys.
