Hi Coinery, welcome to the Forum!
I'm guessing you are Guy, we exchanged emails recently?
We have another member called Coinery (not The Coinery), Stuart, but he is taking a break from the Forum at the moment ...

If genuine, that is a half groat - the 2 pellets to the right of the bust denote two pence (half a groat)
My guess is that it is a low grade genuine example of a half groat
One good reference book on Charles I coins is Sylloge of Coins of the British Isles (SCBI) Vol 33 - The John G. Brooker Collection
My favourite period is pretty much the whole of the 17th century
I do not any longer regard these as coins of the realm, I see no difference between these and some tat produced by Westminster or The London Mint Office
Yes I know they are 'approved by the Queen'
Chris' group is designed to test the RM's narrow definition of legal tender - so far no-one has posted that they have been able to pay court fines with these coins!
And yes, virtually nowhere to go!
I imagine the response they would give to a FOI request would be the (or their) definition of legal tender.
Interesting posts in Chris' Facebook Group ' Pay your court debt/fines in £20, £50 and £100 coins NOW'
Greed has got the better of them imo
