1905 A, 1 Pfennig With Repunched Letters On Reverse

I was going through some more of my world coins and came across this example. I am aware there were upwards of 13 Million minted but I was curious if anyone knows if this was common for the time period?

One of the "E" letters on the reverse looks re-punched, also the "F" in "PFENNIG" looks to also be re-punched, if you look on the top of the "F" on the right side you will see a notch. When looking online at other examples of the 1905 A Pfennig there seem to be none that show this.
