OK 1991 D Quarter No DDO Or Reverse That I Have Found

@hlw, I am seeing MD on several letters of IGWT.

More of an issue if extreme die wear. The wear pattern is towards the rim, but some devices are advancing from die flow lines. These will make the design mushy and affect the fields around the devices. This is not hub doubling, but extreme die wear. On a doubled die, the hub doubling is present from the first strike forward. Die wear is like aging to humans. The older we get, the more issues that develop. That is what you are seeing. Oh, it gets much worse.








This is the die wear on the older multi hub coins.

On the single squeeze dies it is more or less in the same manner:










This is the direction they dies are headed to. As already mentioned they are spiraling down as the die is continued to be used. The first coins were totally normal dies, the coins were all fresh looking. But this could also happen to a doubled die just as well. But these don't become a doubled die. They are just part of the die aging process. (Just like a worn out car doesn't become more desirable with the more miles racked up on it. Same for dies) A doubled die starts off from the first strike as a doubled die. If noticed they are pulled from service and retired immediately.

You will probably learn here more than any other place, as we are probably the only ones explaining this. With so many examples posted here in the past, my files are filling up with more information daily. But that is what is going on with the die that stuck your coin.

Thank you coop
