Fiji 1936 Penny
The centre hole has been punched off-centre. The hole was punched in the planchet before the coin was struck.
It’s not too hard to find coins with off-center holes like this one. However, it’s not common to find one in such a nice grade. If you look at the shape of the hole you’ll note that it is indented where the coin legends and devices finish on the edge of the hole. This is because when the coin was struck the metal in these areas flowed into the empty hole. This is an indication that the holes on these Fijian pennies were punched into the planchet BEFORE the coin was struck.
The rarest split planchet coin error struck after the planchet has split in half. 1.34 grams.
