Lamination or Crack running through the Date? Top of Columns two and four are bridging at the corners on the Reverse? Die Clash at the side and near the top of T in Cent on the Reverse? Memorial sides are Doubling near Column 1 on the Reverse? I reviewed Wexlers Die Varieties Memorial cent Doubled Dies but I did not see anything listed. Any thoughts much appreciated. Thanks.       |

on Obverse: Linear Plating Bubbles it would seem. Goes across the details of the bust, this indicates a planchet problem not die or strike.   Of these, RED is PDD, Plate Disturbance Doubling or DDD ie deterioration Doubling, either have same effect. BLUE is normal imprint Edited by Crazyb0

Ok, I guess some type of contamination on the planchet caused the Linear Plating Bubbles?

Possibly plate splitting on the columns.

Anything left on the blank of zinc prior to plating and upsetting, whether it be a speck of dust or moisture, hair/lint...anything organic will begin the corrosive reaction once plating is applied. Zinc, copper and a catalyst is really a micro battery, like a car battery in miniature.

A lot going on with the first coin. But nothing to bring a premium. The mark on the 'T' on cent is Die Deterioration. Always towards th closest rim direction. The extra columns inside the bays are part of the design.  The marks outside of the columns are either split plating or field reduction from a die polishing. Just events that happen during the striking process. |

Hi, It's my first post on this web site. I have a 1992-D too! The distortion on the surface is more pronounced on mine but we have the same "cracks" in the copper layer revealing the zinc layer below. I ran across this forum/post while trying to do some research on this coin and only found the penny last week. Thanks, Dean      |

Linear plating bubble on the first cent/image. Not sure if this is one or more coins. (best to keep the coin count to one on a thread. It helps avoid confusion)
