Welcome to the forum, the coin has all the proper diagnostics and none of the known diagnostics for a struck counterfeit, it looks to be genuine SVDB. Here is a photo showing all four obverse dies and how the mintmark lines up for each one. I think it was @JKK who mentioned die #4, from your photo the mm looks to be closer to die pair #2 to my eye.
I would grade the coin as MS62 without the obv scratch, however I think that scratch would result in a details grade and is the most likely reason this coin is raw. The carbon spot on the rev is unfortunate and rather unsightly and part of my reason for my grade of MS62 as without the spot and scratch it has the details be a solid MS64+, the luster is muted and the other reason for my grade. Keep in mind that my grade assessment is biased only on the photo and an in hand exam might yield a different grade opinion.
From a personal standpoint my eye is immediately drawn to that carbon spot on the rev, and something like that if it bothers you now it will always bother you. As such my recommendation is to keep looking, 09 SVDB's are not rare at all and with some patience you will be able to find a nicer example for this money level.
