That looks like the right mark and placement (I just checked on it). The wear on the mark is in line with the F12-15 wear on the reverse and the absence of the pearls is consistent with the VG10 obverse. My opinion is it looks genuine.
If you want a certified second opinion, send it to a major certification service. ANACS is good and relatively inexpensive.
I think that it is genuine. The mint mark looks to be correct as well as the rest of the coin. Here is a Mint State example you can use for a comparison.
