The images are not showing errors unfortunately. These are zinc bubbles where dust was trapped under the layer of copper on the zinc core coin. It's common to see these on the earlier years of copper plated cents.
Once the bubbles open up and expose the core they, can start to corrode resulting in the dreaded Zinc Rot.
