The black 'carbon' spots are actually sulfides and oxides of copper. Impossible to remove now.
Oxides and sulfides of copper are black.
For spotting to occur in a yet to be issued roll of coins, there must have been a contaminant on the coins or the wrapper, or both.

Thanks for opinions there were several with smaller spots and in two rolls of the same year/mintage
And a very slight toning on five of my 1958s I wrapped them in tissue and stored them in a plastic coin container
I can't chance them further defacing the beauty

Spotting in this color spectrum can come from a combination of insecticide and common household cleaners in the ambient environment.
Cupric Acetate is in many insecticides. Ammonium Chloride can be a by-product of using Ammonia-based cleaners on surfaces that also have been cleaned by Chlorine-based cleaners, such as bleach, or of bleach-washing dirty diapers. Tiny amounts in the ambient environment could be sufficient to make these spots over time.
Even if the coins were stored in a proper environment by the collector, where were they stored before the collector acquired them? My bet: in a basement, near the washing machine, where a pest control company regularly sprayed for bugs.
The damage is permanent.

Thank you @fortcollins for the tips and insite as to the culprits
I am going to check other re-packed rolls to see if they too are infected as well or just unopened and uncirculated

This is verdigris from improper storage, not carbon spots. The black is cupric oxide - the terminal state of copper corrosion. You can see the green center spot (verdigris) in most of them. This corrosion is very advanced and has ruined any coins you see it on.
Since verdigris can spread across coins and completely ruin obw rolls, the rolls MUST be cracked, the corroded coins removed and quarantined and the good coins put into tubes.
I've opened hundreds of OBW rolls and found many with coins like this inside. It's major problem and the dice you roll buying OBW rolls as you never know how well they've been stored. There are a lot of thread on CC discussing the issue.
GOOD LUCK!

Thanks again @BadThad glad I got those before they caused further damage and glad they did not spread to the whole roll

I found this in a tight, OBW roll. You can see where the corroded, brown coin caused the AU red coin to corrode inside the roll. I had to pry these apart with a surprising amount of force.
Wait what ; You found that corroded Lincoln in an OBW roll ? From my experience that's only possible if the roll wasn't a solid date BU roll or someone threw that piece of junk into the hopper of mix date Cents , actually I'm assuming it wasn't an OBW solid date roll ,but just a common Bank roll of mixed dates . IMHO with all do respect .   |

FWIW, I don't believe there is any such thing as an actual OBW roll of 1958, 1969-S, or 1972 cents. There is simply too much upside for people to crack and re-wrap. Ditto for purported mint bags of these dates.
Crimpers are available for under $30, and look-alike cent wrappers are also readily available. Banks haven't wrapped coins for over 15 years (all that is done by armored carriers now), and commercially wrapped rolls almost always have the name of the armored carrier today. The FRB of St. Louis and American Bankers Association standardization of denominational wrapper colors occurred in 1965. For pre-1965 cent rolls, a variety of colors were in use, and many (most?) legitimate rolls would have been rubber-stamped with the bank name. Especially for 1950s and earlier cents, red-color crimped rolls would have been far less common than what appears online, and most of those wrappers would have faded to dusty brown by now. Mint bags easily can be re-sealed by anyone with access to a commercial sewing machine.
The only commonly found verifiable OBW cent rolls are the high mintage coins with no meaningful varieties from the 1970s and 1980s. These exist in abundance and rarely appear online, because the shipping cost exceeds value.
