1988 P Jefferson Nickel Die Clashes Or PMD, More Pronounced On Reverse?

very nice example!

Agreed, a Die Clash and Die Deterioration.

I like it, nice find.

That is some very severe Die Deterioration. I like it.

This nickel doesn't seem to be the same as the one in the link.
And the differences don't seem to be caused just by the severe Die Deterioration (because of the die state).

Very similar, but subtle differences.
-The area to the left of the dome
-The horizontal line at Jefferson's eye doesn't appear to be on this coin
-The horizontal line at the que (hair tie) is slightly higher on this coin.
-The line at the base of "FIVE"

Pete, I can kind of see what you are arguing. For example, the reverse ribbon clash seems to connect with Monticello at a different place on the roof. However, the clash listing seems to be an earlier die state with defined steps and clean lettering. This example has a considerable amount of Die Deterioration melting, and that will definitely shift devices and surface features.

In order to really analyze it, I think we would need to take the clash listing and then age it as if all the features were suffering severe radial die flow, and then see where the features ended up.

It's a fair point. I don't personally know enough about die clashes to tease apart the subtle differences. I would do it by markers, but given the soft butter appearance of that die state, I rather think that the comparison markers would be deteriorated beyond matching.
