Kennedy undocumented errors - Spitting Kennedy, Blowin'-in-the-wind, Un-Ear, Ear-Cud

[DylanGrace]

I was viewing some rolls of Kennedy half dollars my father saved that were listed under four separate titles. They were all labeled undocumented, along with their respective error names he assigned to them. These are full BU rolls, and I have posted two photos from two different coins for each error, since a total of eight photos is all that is allowed. I can post additional photos later, if needed.
What I am wondering is - has anyone seen these errors before, and what should they be classified as?
The first set is what my father called "Spitting Kennedy", I'm guessing he got that from the "Spitting Eagle" Morgan dollar.
The second set he call "Blowin'-in-the-wind", which looks like Kennedy has wind blowing from the back of his head.
The third he referred to as "Un-Ear", meaning unfinished inner-ear...I'm guessing.
And finally what he called "Ear-Cud". I'm note sure this is a cud though.
I have searched many forums and listings of errors throughout the internet, and have note found a single example of these errors. Maybe someone out there is familiar with these or can help me classify them correctly.

The photos are clear, thanks for that. Assuming the Kennedy weighs in at the right amount, and the size of the planchet is correct, I think its one of two things. Its either one heck of a grease filled die, or they simply overheated the planchet and struck the coin pretty soundly. Typically greasers will fill the dies with grease and some of the devices can clogged and not appear on the coin itself. It would be nice to see a full obverse and reverse of this. Mike Diamond, who typically hangs out on the mint errors side of this forum might chime in here and give his professional opinion.

Typically CUDS touch the rim of the coin in order to be classified as a cud.

Dies typically wear out over time. Add in that sometimes these planchets are not necessarily struck perfectly each and every time. Some times machine doubling (the worthless style doubling) can knick or remove portions of an affected part of the coin. These are more of a mint error than a die variety error.

Two things that would be helpful would be the YEAR of these coins, and a full photograph of the Obverse and Reverse.
