I did a quick look: doesn't appear anyone has listed a 1983D yet. Here's a P that looks like your clash. Fun find! Reach out to the folks at Mad Die Clashes. They may want to list it. CCL(TI)-1c-1983-02 : Mad Die Clashes
That's a very cool clash. I thought I saw a counter clash in there, but it is only die deterioration on the right side of the ERTY.
