Searching Half Dollars.. Found Brockage Error Cent Lincoln

I am about done searching half dollar bags, as the silver seems to have completely dropped out of circulation, but I did find some interesting stuff in this last bag, which I picked up on Wed.

o an angel type token
o 50p UK 2008
o New Zealand 50 cents 1967
o Battleship Oregon medallion

And what seems to be a brockerage error penny, perhaps with other errors, on a 1968 S penny.

The obverse has an obvious negative imprint Lincoln memorial rotated about 80 degrees. The letters CENT are clearly visible, clearly reversed, opposite the nose on Lincoln's face. Pluribus Unum is also obvious, as is "States of America", and and easy to read, reversed, behind Lincoln's back.

The reverse also has a reversed Lincoln Memorial rotated 80 degrees. E Pluribus Unum is clearly visible reversed to the left of the Lincoln Memorial.

On both sides is what appears to be an offset error, creating a ring set into the coin surface, but the coin is perfectly round.

Coin is slightly domed from obverse to reverse.

I almost feel as if there may be multiple errors:
o brockerage error, in which the previously punched penny stayed in the (upper?) die, and put a reverse Memorial image on the obverse of the penny.

But there is also a reversed Lincoln Memorial on the reverse of the coin. How did that happen?

o Is there also an offset error?

Anyway, fun find, and anything that someone could share to explain how this happened would be appreciated.
