1776 Coin And Wanting Some Information On (Id: Likely Contemporary Counterfeit Half Penny)

to the CCF

We can't help much without seeing the coin.
Supply a large clear photo of each side so we can see the details.

That is a George III Halfpenny. There were no halfpennies struck in 1776.
It is either an US Evasion piece or a copy, I am not familiar enough on these to tell the difference.
Perhaps one of our early coin experts could weigh in on this one.

You're in England, so I'd assume it's a local counterfeit, rather than an American one.

Counterfeiting was very common in the late 1700s. A majority of the halfpenny "coins" circulating in the 1780s were either counterfeits, or "evasions" - medals designed to resemble coins, but with some design or text changes to try to get around anti-counterfeiting laws.

Counterfeiting was of course illegal; numerous convicts despatched to Australia were convicted of forgery. Some of those forgers even helped make Australia's first coins after they got here, putting their coin-making skills to official use.

Isn't it 1775?

I don't know if counterfeits made in Britain at that time would have had correct legends. You risked being hung for trying to pass off, when you could just change the legends to something humorous and spend the fakes without consequence.

Perhaps not quite that old. The counterfeiters often deliberately made coins that looked old and worn, and gave them suitably "old dates" to match. The late 1780s was the height of the halfpenny-counterfeiting era, though it could date from the 1790s or even early 1800s too.
