yeah what does the reverse look like ?
I would think similar to allow that much metal to build up.

The reverse was struck normally. So it is just a misaligned die strike on the Obverse and it is not a dual misaligned die strike as the link provided shows.

Keep looking at more cents especially the 1970"s and you will notice a lot of this type of issue.
