Identify coin with very few details still visible

Hello guys,

Can you help me me that? I have got this coin or token, but almost everything is gone!
There is a "GEORG" and a "Rex", and what remains on the other side looks like a Farthing, so, I'd say that it was a George III Farthing.

But it's bigger and heavier that it should be, its diameter is around 35mm, so maybe it's a token which copies the Farthing design, or just an other bigger coin that I don't know ^^

Here are the photos (sorry for phone camera quality) Hello guys, Can you help me me that? I have got this coin or token, but almost everything is gone!

So quick, thanks!

Easily identifiable, to me - and in those days the same design was used on four
coins as they did not at the time put a denomination on. Approximate sizes ...
1/4d (Farthing) = 21mm
1/2d (Halfpenny) = 27mm
1d (Penny) = 36mm
2d (Two Pence) = 41mm
The only difference between them is the size.
And those last two, because of their large size, were nicknamed 'cartwheels'.

Nice to hear that, I learned something today!

Another curiosity for me that I think I'll post, I have a 2 centavos from Argentina of around 1890, but it has only one side, nothing on the other, and it's thickness is half of a classic coins.
It's as if they minted the two faces separately, and then put the two sides together! Strange ^^

I don't believe there were ever any Cartwheel farthings/halfpennies (unless you count the Isle of Man issues)?

@Cass

Yes you are right. The George III farthing and halfpenny do not have same style. Isle of Man has cartwheel half penny, but not a cartwheel farthing.
