Searching 40% for errors, are these double dies or machine doubling?

[Ben Cartwright SASS]

Today I went through a bunch of 40% Kennedys and found several that I wonder if they are double dies or machine doubling or what?
I bought a small bag of 40%ers from a local coin shop and going through them found 9 90% Kennedy's and what appear to be doubled Obverses, maybe?

1st two pictures are a 1966


2nd two are a 1967


3rd three are a 1967


4th three are a 1967 with doubling on 9 OD and neck and W


5th 3 are last 1967

I see a lot of machine doubling. Sadly, I see no sign of die doubling.

Should anyone see something I missed, I am sure they will chime in.

Time for more coffee.

I am afraid you are probably correct. Yet it was a fun search as rather than just stacking them I searched them and also found 9 1964 Kennedy's in with them!
