2001 D, 1994, 2002 D Lincoln Cent Errors? Need Some Info Pictures Included !

The first picture isn't loading for me but the last two are both plating bubbles.

Same for me, the last is a "linear plating bubble". Something got between the plating and zinc core that has caused corrosion to start. Lines are usually hair, or fibers. The bubbles can be any kind of debris or liquids.

The curved bubbles makes me wonder if a coin wrapping matching didn't aggravate the corrosion to form a ring. Most times a "split plaiting" error happens, is the stretching of the devices, here, the date, when stamped. This may break the plating exposing the core to the elements. Its only a matter of time before corrosion sets in.

Hello to everyone thanks for the quick replies and the more information I learn the better have to take the good with the bad #128526;
