Upon first looks i am not liking it.
I don't like the look of it either. I have never seen a Totenkopf disk stamped like this one. I would say it is fake just from the physical characteristics of the stamping (without getting into the way it is stamped which is also suspect). The "3" stamped in the lower left quadrant and the "B" in the upper right appear to be stamped over the corrosion and halo significantly. A better photo might help but for my collection I would not own it.
I could go into a few pointers but the main thing i see is the Strike Font and positioning.
Font and haloing kill it for me...
Nothing there to make me say it's legit. Can we see the reverse side ?
Imo it is a fake!
I concur with all the above i'm not liking it !

Thought shall be the harder , heart the keener,
Courage the greater as our strength faileth.
Here lies our leader ,in the dust of his greatness.
Who leaves him now , be damned forever.
We who are old now shall not leave this Battle,
But lie at his feet , in the dust with our leader
