1976 proof penny misaligned die

I bought a proof set and came across this is this normal or valuable? The penny’s back is misaligned.

They are not tight fitting in many of the sets. I have many where one or more of the coins inside have moved. Here is an example of one of mine

 

Looks like a slight rotation of the die. Not enough rotation for any extra value.

 

Now I want one

 

Lol

 

True but the thing is is on one end the penny is completely straight the other side is crooked.

 

It has to be a fairly large die movement. I would only be interested in one approximately 180 degrees off with the die.
