Greetings, 1998 cent on both the obverse and the reverse you can see a DD I appreciate your valuable opinion. Thank you

In my opinion, it looks like either post mint damage or severe mechanical damage. It looks like damage, rather than some sort of doubling.

Excellent information and I continue with the education…every day I am more passionate about the errors and variants of the currencies. Grateful.

The ground thruth for the doubled dies and the repunched mint marks is that they have not been created for quite some time when it boils down to doubled dies prior to 1996, and no re-punched mint marks (RPMs) since 1989. The resources are drying up, so expect to see less finds in the future.

There are a few cases of newer "doubled dies", but the process in which they were made is not the same as prior to 1996. It now involves a single squeeze technology, where doubling occurs when the massive amount of pressure is applied to the working dies, and they moved slightly.

Prior to 1996, they used multiple impressions (called hubbings) to the working dies ensure the images of the coin were transfered correctly. Occasionally they moved the die in between impressions to see the image progress. If the die was not placed exactly in the same location and the die received another impression, it may have been slightly off, and a doubled die was created.

Modern minting methods have greatly reduced the frequency of these varieties due to the use of a single compression axis method during die creation, but duplicate dies are still produced on modern United States coinage. With the new die manufacturing process, implemented after 1996, the dies only required one impression of the center to transfer the entire design from the center to the die. But it has been found that the pressure created is so great that some dies tend to rotate slightly during this process.
Modern duplicate dies on US coins are being discovered primarily on Lincoln pennies. The 2004 Peace Reverse Nickel shows duplicates in the date, motto, designer's initials, and Thomas Jefferson's eyelid. The 2005 Bison Reverse Nickel shows a slight doubling in the word "Liberty" and other devices on the coin.
