As there are few images of this coin to be found, here's a visual comparison. All details are from coins with the same date and mintmark.
Left - images available online (catalogs, auction houses).
Right - this specimen offered on
ebay.
The mintmark is completely different. While there seem to be versions with and without dots, when there are dots they're small and clearly separate from the letters, not almost touching them. The W is always higher than the M, not lower. The letters are thin, not thick. There is a serif on the top right of the M, not bottom right.

The points of the line dividing the denomination and date are sharp, not blunt.

O is always lower than K, not on the same level. The serifs are thin, not thick. The right-hand side lines of the K (both the one that goes up and down) are straight, not bent. The O does not have a weird missing part at one o'clock.

The end of the 2 is sharp, not blunt. The dot is much more defined. The bottom-left point does not slope downwards.

The top horizontal bar of the last letter in the 3rd line does not extend beyond the vertical one and has a tiny point, while here it does extend far beyond it and has no point. The dot right below this letter is visibly larger, while here they're unevenly placed but of the same size.

Many other differences exist, such as how O and M in the third line are too close together, thickness of the S etc. And that's just one side of the coin.
