The numbers seem disproportionate in size. The "8" dropping in the back surrounds the one on top, as if it were much bigger, instead of crossing through as being superimposed if they were the same size. I think this is an example of die deterioration.
You have several things going on here. One is the die chip (not a cud) on the one of the date. Two, there is die deterioration doubling on the letters which is caused by an over worked die. And lastly, there is machine doubling. The machine doubling is caused by vibration, or die bounce, after the initial strike. It is easy to determine if you look at the tail of the 5, where the previously struck digit is struck again by the bounce and has made the original tail seem smaller, and the doubled part look squished or flattened.
The 1958 Doubled die I think is the one with the high premium for the year of 1958 with regard to Wheat Pennies. It's a wheat penny, right?
