Is this Doubling or Degradation?

RTSatre

Hey coin fam. I have this 1976-D 50C Clad Kennedy. It is worn, but I think I am seeing doubling on the reverse. I have mostly just been looking at pennies, so less trained on what an FS-801 would look like on these. Adding a few pics.

It looks like doubling on the words and windows, but I only see DDRs for the S proof Kennedy this year, so it seems a little unlikely. Is this mint doubling, or is this just an aspect of the stamping one sees when the coin wears down a little?

Thanks in advance for your help and guidance.

That does not look like a doubled die. The following illustration (I did not produce the illustration) should help you regardless of the series or denomination.

Sorry. This is a bicentennial, of course.

Yes, there is "doubling". No, it is not a "doubled die". It appears to be mechanical/machine doubling.
