You can see best on the date how it "cuts into" the devices rather than adds to them. That is indicative of mechanical (shelf) doubling. Also, without the presence of any prominent notches or split serifs, I do not see any evidence that this coin is a doubled die.
Ditto to what Simon had pointed out. For this era of coinage, it's typically referred to as Longacre Doubling and adds no significant value.
Maybe you can correct me, but I thought Longacre doubling was a different anomaly than MD? I thought they were caused in different ways?
