Question on spotting on the 2009 series

[Guest]

What are those tiny black spots the 2009 LMC's are plagued with?
Is this water spotting or is it verdigris?

I haven't see an overabundance of spotting on the 2009 cents (They wouldn't be LMCs because they are not Memorial's) I looked through thousands of rolls. Any time you do see them, it is either a final rinse issue at the Mint, or something happening to them before they were wrapped. It wouldn't be verdigris...but corrosion if I am not mistaken.

I can't believe I called them LMC. I meant to write LBC.


Thanks for your quick reply Bob, but I'm surprised that you haven't seen an overabundance of spotting on them. I've been reading numerous comments from the past 2-3 years and just about everyone has been complaining about this.

But anyway, some people call them 'water spotting' and others 'verdigris'. I wanted to be sure which one it is.
Is this corrosion from oxidation, and does it get worse(ex, dots growing in size) on the coin as time goes?


Just to be sure... I am talking about those numerous tiny black dots that are found all over most 2009 coins.

Thanks,

LSC is what you want..but I haven't seen black spots either.

There were so many minted that is is quite possible I just plain never saw a bunch of them. I guess at this point, it really doesn't matter unless you are trying to find some nice spotless examples. The carbon spots usually come as a result of a contaminant on the surface of the coin and moisture of some sort. It literally eats into the surface of the coin. Once there, it will never go away. If the spot is all black, it is probably not going to grow. However, if there is a greenish color in the middle of some spots, it will likely continue to grow until something is used to halt to corrosion process.

LSC ?

Aren't they LBC (Lincoln Bicentennial Cents) ?

Why yes they are...I completely forgot

I have seen a lot of "sneeze marks" on 2009 cents. They are not carbon spots, but make the coins look like crap.

I know exactly what you are talking about.

"Sneeze marks"? Even on uncirculated coins from sealed boxes?

Who did the sneezing... Lincoln?

Oh I crack me up sometimes!

[copperlover]

I would call it corrosion from saliva/sneezing or water. Take a clean coin,put some tap water or saliva and watch the development of the corrosion take place over time. It is acid from the contaminants at work.

Sorry to bump this, but as the self-appointed terminology/acronym police, I felt a follow-up post for other newbs that may view this thread was important. Bicentennial means 200 years. In 2009, the Lincoln cent turned 100 years old, so LBC is definitely out! Not sure what LSC would stand for. Help, Roger. Would we call them LCC, for Lincoln Centennial Cents? We currently have no general acronym to describe them in the list beyond the LP1, LP2, LP3, and LP4 listings. It doesn't matter so much, but I just didn't want people throwing around anymore new incorrect acronyms. Don't mind me, had a rough night of sleep.

It is actually a good point Will. Technically, the 2009 cents were issued to commemorate two different events. The Bi-Centennial of Lincoln's birth, and the Centennial of the Lincoln Cent.

Lincoln was born in 1809, or 200 years before 2009, hence the bicentennial celebration of his birth. I would argue that the designs in 2009 were meant to commemorate his birth rather than the production of the first Lincoln cents because the first Lincoln cents themselves were made in 1909 to commemorate his birth.

Edit: Ninja'd by Bob once again, lol!

The spots stain the plating, thus making it ugly and undesirable to us.

According to Wikipedia:

The Lincoln Memorial reverse was itself replaced in 2009 by commemorative designs marking the bicentennial of Lincoln's birth.
