The area in question if you look at the shape of the digits, nothing is larger as you would expect on a doubled die. They are all the same size with just some metal pushed from the ejection of the coin from the mechanism.
Note on this coin which is a small date over a large date 1960:

Note the size that the digits are increased? The die is doubled and every coin struck with that die will look just like that. Hope this helps.
Here is a circulated example I found. Compare with your coins image.
