Looks damaged from having a another coin hot on the reverse leaving the rim incuse mark and flattening the obverse devices. Not a doubled die or a double strike. A double strike would show on both sides and the first strike would be almost removed.
Flip over strike:

Rotated in collar strike:



Yours is just a damaged coin, probably placing two coins together between a couple of 2X4's and smacked with a large hammer.
