That looks like the real deal to me, but I have never seen this variety in anything below mint state so I can't say for sure. Here are some photos of some mint state examples. I don't have a photo of the die gouge that created a spike, but I know that the spike points at the top curve of the 3, not below the midpoint as the example shown in the OP. @ coinrookie85, can you give us some full coin shots of both the obverse and reverse?
Sorry best I can do. A bit of glare so I could get good detail shot with cell phone. Hope these help. I pressume the coin to be in f-xf but not good at grading.
I would say that your coin is in the VF range. I was only able to locate one other auction record of a 1943/2-P in that grade range. http://coins.ha.com/c/item.zx?saleNo=131118&lotNo=28716#Photo The coin was a 1943/2-P graded VF20 by NGC. It realized $59 in 2011.
This one is the real doubled die. You can tell by looking at the lower curve of the 3. If the inside curve on the bottom is flat (like yours) it is the 43/2. The gouge/spike will have a normal curve there. The reason the 43/2 is flat/straight where that curve should be is because the horizontal bottom of the 2 fills that curve. Great class 3 doubled die example.
Don't know that it would add any value but it also looks like there's a lamination crack bisecting the bust from 12 to 6:00.
