Random shot of 1c 1970D obv. at 200X

Random shot of 1c 1970D rev. at 200X

this is a shot of a 1964 1c obv at 200X that I feel is for sure acid treated.This coin is about same size and weight as 1970D>The look of the 1964 says ACID.
My question is it possible to achieve either effect with an acid if the whole coin is treated?
I am not a chemist and have no clue.
Thanks in advance for any help.

lenght of application cause the affected coin to look different. While it's certainly
possible that there was a real problem with the cent when it came off the die, it
has been obliterated by the apparent exposure to a chemical.
This specific coin looks like it may have been in acidic soil, but this can be impossible
to confirm also.
