Hi all, brand new member here :)
Have a query about an old 1912 English penny. I'm trying to ascertain if it was struck on the wrong planchet or not. It appears to be a gun metal grey/black colour, and I cannot find another coin of it's colour online. I initially thought it was environmental, but I just can't see any of the typical copper red colour on this coin such as streaks or blotches etc. I'll attach some pics of this. Out of the 1000 English/Irish pennies I have this was like the ugly duckling. There's no other penny with this colour. I've compared it against a 1916 English Penny so the difference can be seen.
