1992 D DDO DDR Possible Triple Die Reverse? Have You Seen This Lincoln Cent?

to the CCF

Your coin exhibits classic Machine Doubling which is not a true doubled die at all but a result of how the coin shifted while being struck.

The flat, shelf like devices on the 2nd 9 in the date is a text book example of this phenomena.

It's not considered a collectable variety or error - simple a common striking occurrence. It the mint required every coin to be perfect we would have very few coins.

I am seeing DDD and split copper plating.

the deformations on the device elements are/were caused by a worn die.

There are many types of doubling we all need to learn,here is a link for you to study and book mark:https://koinpro.tripod.com/Articles...Doubling.htm

This is DDD. ( Die Deterioration Doubling) Note that the fields are the areas affected, not the devices. These are always towards the direction of the closest rims. Thus on the Date, you see them on the right side of the coin. On Liberty you will see them on the left side of the coin.

These are not doubled dies and will never be listed as a doubled die. They are extreme die wear on the dies. Common to find on these single squeeze cents. There is actually a 4 step progress that these dies suffer. This is just the fist stage:

There are three other steps beyond this. But not a hub/die creation, but die wear on these cent dies. To learn more on this subject check out the link below:
DDD? What is that? stages of die aging. not a premium for the coins, just what is going on with these single squeezed dies with the lower profiles.
