Have you done a search on Variety Vista or Coppercoins.com? If so what did you find? Remember that these are not likely to be found for the first time in 2021. After all these years and so many eyes would it not have been found and reported? Not saying that new discovers are not made, they are. But, the odds are pretty slim on common US modern coins. The last one that I remember taking some years to discover was the 2008 American Silver Eagle with the reverse of 2007. For some reason this went unnoticed for many years. But, then again it's not a circulating coin either.

Remember that in 99.5% of the time, doubling
you see on any given coin, any given denomination,
will be what is called 'ejection/mechanical' doubling,
and not the hoped-for Doubled Die..........

Wexler has good explanations of the die making process and the characteristics of true doubled dies, Mechanical Doubling (also called strike, machine, and ejection doubling), and Die Deterioration Doubling. If you take the time and study them, the confusion will start to fade and you'll start recognizing them a lot sooner.
While you're there, start looking at his pics of known doubled dies. Notice the split serifs, rounded (not flat) impressions, and letters/digits that aren't thinner usual

I won't tell you it's mechanical doubling.
It's ejection doubling - that better?

Kennedys are my quest...
Yes... more mechanical doubling. I tried not to tell you, but the facts are clear. Cheers, RickO
