This is fairly common on the 1992-D cents.

Die Deterioration Doubling
Die Deterioration Doubling is a very common type of doubling that adds no collector value to a coin. Many new collectors will confuse this type of doubling with the more sought after doubled die varieties. Die Deterioration Doubling, like a true doubled die, is on the die itself, and not an error in striking like the Mechanical Doubling is. Die Deterioration Doubling happens when dies are over used and the details begin to deteriorate. When the planchets are struck by the die, the metal flows much like a footprint in muddy soil. After a while, the dies will erode just like water or any other flowing material will erode the surface it flows over. As the die erodes it forms depressions in the die which will leave raised areas on the coin's surface. The doubling from deteriorated dies will have a much softer appearance than a doubled die, which has a sharp detailed secondary image.

plus, on a couple of those areas, it looks like the copper plating has pulled from the zinc foundation.
