1989 D errors

[RandyK6371]

These pictures are of the obverse and reverse of the same coin. These are not shadows. The thing that I don't understand are the shifts go in different directions. As I have said, I am new to these magnified pictures of this nature so I am still learning. I need help understanding what I am seeing.

These are closer on four locations.

In your case some of the plating is merely disturbed and not yet split, but this is what you have.

Split Plate Doubling (Split Line Doubling): This occurs only on copper-plated zinc cents struck from mid 1982 to the present. During the striking of plated cents, the plating (http://www.lincolncentforum.com/terminology-list-p/#Plating) is stretched in order to form the raised design elements. Whenever relief is created from a flat surface, there must be expansion of the overall surface area, thereby putting stress on the plating. Sometimes, the plating will split on the rim-side of the devices, exposing the zinc core. The exposure will be in the same shape as the design elements, thereby creating a “doubling” effect. The exposed zinc is blue-ish in color. In addition to the examples shown below, please also see Jason Cuvelier’s thread on the subject Here (http://www.lincolncentforum.com/?s=split+plate):

Cool looking... That gets new folks all the time and even some of us that have been around for a while (like me :LOL_Hair:)... Can you get a full obv and rev pic??? It looks like you have some heavy die wear but I can not tell for sure???

89 is full of these, split plating or some with ghost doubling from die deterioration towards the rim.

I agree there is also some die deterioration doubling.

Awesome... Thanks for the follow up pics... They are just fine... Your obv die is really worn and the rev not as bad... Here is a tutorial, on the forum, about Die Deterioration Doubling (DDD) (http://www.lincolncentforum.com/die-deterioration-doubling-ddd/)... Here is more info from Error Ref (http://www.error-ref.com/?s=die+deterioration+doubling)... Here is some info on Ridge Rings from our Glossary -

Ridge Ring: One of the many manifestations of die deterioration (http://www.lincolncentforum.com/terminology-list-d/#Die%20Deterioration), a ridge ring is a circular area of distortion that goes around the perimeter of a coin near the rim and is the result of cold-metal flow toward the rim from the striking process. These are most commonly seen in the 1980s. Photos courtesy of jay4202472000.
