There is definitely a bust facing to the left it is clear to me...so now look at coins with busts facing left..also what is the diameter in mm.
King George II and George I face left as do the matron head and coronet large cents. There are other coins as well but this is such a classic looking KGII or LC...I dig em like this all the time. They go in my box I call the tomb of the unknown coin.
I took the top pic and did some overlays of coins in photoshop and a King George II aligns up pretty accurately but a lot of detail is gone on yours so it is close but can't say for sure.
The Large cents actually did not align up well with the hair and the nose and chin.
Also something alot of people are not aware of is that a stagering number of KGII coins are counterfeit...they counterfeited the heck out of them in the 1700's. I read the percentage estimate and don't remember it but it was like 30% or something crazy which is why KGIII did not export to the colonies prior to the revolution.
So KGII's can vary due to this...just a silly fact
