Hello Ozz, and welcome!
I have an '09-SVDB with a similar level of wear and PCGS graded it VF-35. I agree that your coin looks softly struck on the obverse, with the reverse stronger.
I also agree this one might not be graded at NGC or PCGS. The shoulder scratches might cause a reject, plus the spotting could be corrosion. Can you determine whether the spots are just discoloration, or are there pits that penetrate the surface? If there is corrosion, you might consider sending this coin to NCS for conservation. They can professionally process the coin to stabilize corrosion and prevent further damage.
