Sweden 1875/74 2 Ore Overdate--2nd Die Discovery

For those who collect Sweden overdates, I recently saw something interesting when I compared my 1875/74 overdate to one on a Swedish site. In the photo below, the top coin was sold in Sweden, and the bottom photo is mine. At first glance there are many similarities, but striking differences too. On my coin, the diagonal of the 4 is far more prominent, as well as the shape of the 7 is different. However, the strongest evidence of two dies is the distance between the 8 and 7, which cannot be accounted by die state or wear. As with the 1861/57 5 Ore, there must be at least two 1875/74 overdate dies.
