Help on Pres $1 coin errors

I received several rolls from the Mint's direct ship program and I think I found some good errors but I could help identifing / confirming what I think I found!
I'd also like to get your opinions of these errors, how rare they are, and how much they would be worth!
I took the best pics I could get... the coin 4 pics turned out the best and I figured out what to use to prop my coins up now!
All coins are from the Philly mint (except George Washingtons which were from Denver).
Coin 1 (Obverse):

Coin 1 (Close-up of error area):


Coin 1 assesment:
I'm guessing by the jagged edges & shifted metal that it is a deffective planchet / maybe an air bubble that burst when struck?
Coin 2 (Side):

Coin 2 (Obverse):


Coin 2 (Reverse):

Coin 2 assesment:
It looks like there is some minor waffling from jammed feeder fingers? How do TGPs know that these types of errors are caused from the mint?
Coin 3 (Side):

Coin 3 (Obverse):

Coin 3 (Reverse):

Coin 3 assesment:
Similar to coin 2, waffling error / feeder fingers but more pronounced
Coin 4 (Obverse):


Coin 4 (Reverse):

Coin 4 assesment:
Looks like maybe it was grease filled dies or something similar, especially since the reverse looks well struck and has no errors.
Coin 5:


Coin 6:

Coins 5 & 6 assesment:
Minor clipped planchets
Thank you very much for looking and giving me your opinions!! I have learned so much from this board and I hope that I'm right on some of my assesments!

Coins 2 and 3 both are damaged after strike and would be BB candidates.
Coin 4 has a struck through grease appearance. the missing "ES" from "PRESIDENT" gives it some extra eye appeal. However, the damage to the obverse rim area at 3 and 11 O'clock may make this one BB too.
Coins 5 and 6 I can't really get a good look at based on the pictures but I would guess 5 is a defective planchet and 6 is a 1% (or less) clip.
These are just my guesses based on what I see.
Hope it helps.

It is considered a minor error, worth a small premium.

I'm a little confused on coins 2 & 3, I received the coins directly from the Mint.... so the damage is definately from the mint.
I also found several off-center strikes, but none of them are off of the planchet just not 100% centered. Would these be worth any type of premiums?
Don't confuse physical plant......The mint vs. act of minting.
Simple rule is if anything occurs before or as coin is struck thats OK.........anything that occurs after coin is struck then its not OK.
If a blank got cut in half and then the half of a blank got struck it would be a major error.
If on the other hand a coin got struck then later cut in half it would be post minting damage.
One coin is a Rim Burr (Capt. Henway's reply)
The other coins are damaged after they were struck,
and were probably caught in the rolling machine.
They are not errors.
