Any number of factors could have effected the toning, but it may have made a trip through the wash in a someone's pocket.  I've read that laundry detergent can cause copper to tone in some light pastel shades. |

 it's just Post Mint Damage. PMD. Nothing in the minting process could have caused this. Usually when you see something incuse on one side of the coin with a corresponding area that's raised on the opposite side, it's going to be damage.
Keep searching and post when you have questions!  |

It is a common coin. They minted 3,677,175 so not everyone has one, but they are readily available.
It sounds like the coin has some damage and corrosion, so it would be called a impaired proof at this point. It really isn't worth enough to have it professionally conserved and trying to clean it on your own isn't advisable.

Someone has pressed coins together in a vise to make it look as if it's an error. The reverse lettering is something to look for when the impression didn't come from a die. That along with the other damage on the coin, points to modification, and not a mint error. |

If this area is raised, you may want to soak it in acetone to see if dislodges the gunk. If this area is incuse, I think it's a strike through with retained material (I would leave the gunk in place.)
It looks like it's incuse, but I can't tell for sure. I can also see reflections along the edges that make it look incuse. Would you let us know? 
I have cent with a retained strike through somewhere in my collection. When I find it I'll see if I can get a decent picture and post it. |

| It could be that the difference you see in the other SMS coins just shows a different die stage. Don't forget, while the SMS coins were not struck like exactly like a proof, they were struck with greater pressure with specially prepared dies. The result being that the mottos, legends and other devices are full and sharp. |

It's not an error, it was damaged after it was struck. The area of the coin that is normal has a full rim. This means that it was struck in the retaining collar. The area that is damaged has lots of metal movement that couldn't have happened when it was struck.
It's an interesting coin, but not worth a premium over the face value. If you like it, keep it (I think I would) or exchange it at the bank for a newer nickel. |

This coin was struck in Philadelphia, so it has no mint mark. The only year that a Lincoln cent has the P mint mark under the date is the 2017-P. They added the P in 2017 to help celebrate the 225th anniversary of the mint. In 2018 they returned to a plain field under the date.
The Philadelphia mint was the original US mint. Later as these so-called Branch Mints were put into service, they added mint marks to show where the coins were struck. The mints stopped using mint marks on any coins in 1965, 1966 and 1967 to discourage coin hoarding and collecting. The mint marks returned to US Coins in 1968.
