I don't think so but can't really tell based on these images.

Hey Mike.
Are you talking about areas like the 8's of the date, BERTY, IN and the N of ONE on the reverse that look like the letters are "deflated"?
Not a doubled die if that is the areas in question. I think those areas are where the underlying zinc has started to react and "dissolve" (think zinc rot on a less obvious and destructive level). As the zinc reacts and dissolves away the copper plating fills the void and it looks like the letters are deflating.

As usual Paul's decades of experience pays off.
His explanation of the metal flow into the die devices being a possible culprit is much better than my thoughts.
(The only thing I can think to add is the possibility of low striking pressure, which might add to the metal flow suggestion.)

When I see these "caved in" letters and numbers, I think the zinc behind them has disintegrated due to the copper plating being porous along the letter/number edges. The copper plating is then pushed in to fill the gap.
