Check for plating tears. If air gets under the plating the zinc starts to raise the plating. In time the zinc will dissolve leaving a flattened area under it. I agree the size makes it hard to believe it is a doubled die. Although some doubled dies are not just vertical bars. Some are class 9 doubled dies with the snap into the correct position leaving a deeper area of the die that isn't removed when the complete hubbing is completed.
Here are three that were listed by John Wexler that I sent to him. The center one is the most interesting.

You can see the tilted comlumns that snapped into the correct position.
Here is the link of his new listings and mine is there:
