As others have said I'm not seeing the VDB either. But I am seeing the S mint mark, which looks to be very nearly directly beneath the zero. There were 4 noted die varieties of the 1909S-VDB and none of them had the S directly below the zero. However, die variety #3 of the 1909S regular does have the position of the S that seems to match your photo. Do you have the ability to measure distance between the lower slope of the 9 (the portion closest to the mint mark) and the top left curve of the S? Die variety #3 shows it to be .80mm. All four of the VDB die varieties show the distance to be much smaller, from .29mm to .74mm. The reference I'm looking at is Keys to the Lincoln, by Charles Daughtrey that has a bunch of close-up photos and all kinds of measurements and details about every die variety.
