There are quite a few RPMs for the 89 Denver Mint..

:mad: Unfortunately your image here does not have a high enough resolution for an Internet image to determine a re-punched mint mark.
Looking at the overall coin,... And your close-up, I am going to go with "Zinc Rot".

:eureka:
Many times when these blanks were struck, there would be a slight separation in the plating, leaving small areas exposed to the elements.
The small areas adjacent to the devices would then accumulate the environmental affects of circulation, which in turn causes this 'rot'.

I agree this is a plating issue.
