Need Help With 3 Error Nickels

I'd say die cap, tilted collar and I dont know what. I found an '89 also today with the same surface. Pretty curious piece.

I think the first coin is struck through. Probably from grease but I am not sure. If it were struck through a die cap I would expect more softness in the letters and I wouldn't expect the sharp defined edge of the die at the rim. I think the second coin is die damage possibly from a hard collar clash. The third coin looks like the surfaces were altered outside of the mint.

Keep in mind a die cap and struck through a die cap are two different errors. A die cap is the coin that sticks to the die for more than one strike while the struck through a die cap is one of the coins being struck by this capped die. A die cap usually happens on the hammer die and the collar surrounds the coin on the anvil die so a die cap tends to expand larger with each strike. The most valuable die caps are the ones that form a cup shape from moving up around the neck of the die.

The pebbling on mine looks very similar to a satin finish. It does not look acid eaten or sand blasted as I have gotten sand blasted and it's pretty obvious when you see it. I am starting to think that the first one may be a strike through thick plastic perhaps. It's pretty are specific to the head and front of face area.
