Mr M. I've told you a million times not to exaggerate. It's actually about 3% coin, but I concur re the size of the important bit.
James II penny. Is it 1687/8 where an error has been corrected or 1688/7 where the 8 hasn't been sunk deep enough to cover the 7? Impossible to say.
I thought I saw a coin in the previous image. Much better, thank you That's pleasing, particularly the reverse which has a decent amount of detail for such a small working area. 13 mm or so diameter? And an overdate as promised.
They miss a lot - denomination, date, type, reference numbers, you name it, they'll get it wrong somewhere along the line. (Which can be used to your advantage). I reckon that about 20% of the 200 or so slabs I have purchased were bought on the basis of a TPG mistake.
1773 halfpenny with the first 7 over 1 and 3 over 7. Presumably the engraver started too far to the right.
