I'm working on uploading my Fort McHenry DDRs to my site. This coin is one of my favorite for DDs as there are about a dozen DDRs that are relatively strong for the series and some of them, especially WDDR-001, seem to be somewhat rare.
I've recently noticed that
Die Deterioration can affect this design in a way that can be easily confused with true die doubling.
I have two examples of WDDR-007, one mid-die state and one late-to-very-late-die state. Here's two pictures, one of each coin, of the exact same location:


Now if this is the same die, why is the doubling so drastically different? It's because this doubling not true doubling. It's just
Die Deterioration Doubling. Wexler describes this separation on WDDR-007 as true doubling, but only the extra thickness is true doubling.
Here's the images of WDDR-010, this is the only doubling mentioned in the description:


This doubling looks like, and is in the same location, as the
Die Deterioration Doubling I see on my WDDR-007. I don't believe this one is a true
DDO.
What do you guys think? Do you agree or did I miss something?
Here's some links to the listings for this coin (my site included) if you wanted to look at some of these cool DDOs:
