PCGS slabbed silver dollar... with spot?

[aaron7]

Wondering what happened to this thing! Been in storage and I can't imagine something getting in. Nothing on the slab shows the coin was damaged when it was put in there.

I've seen these as high as $250 recently on ebay! Wondering how much this might hurt the value?

Oh my, according to this I think that spot might just ADD value!

On November 1, 2001, American Silver Eagles were recovered under the rubble of the World Trade Center from the Iron Mountain Vault, this is one of the recovered coins, comes in hard plastic case and certified GEM UNCIRCULATED by PCGS.

I often see these "stains" on BU silver coins. It can be toning from some small spec of debris or a spot of a substance. I have also heard about the "wash" they do to the coins can cause discoloration.

It might knock of a dollar or two, but really doesn't hurt the value much. If a person is looking for eye appeal than they might try to pay less.

That's not toning. That spot grew from a very small piece of grease or debris. It does affect the value slightly. Still a great coin though.

It has too be some degree of toning, a small spot of debris can't grow, but the area surrounding the debris would tone. However, what I am referring too is something that happened to the blank planchet before it was struck, and this can't be removed without damaging the original surface.

I observed this many times with silver dollars.

Don't want to argue but toning will usually happen over the whole coin, not just one tiny isolated spot. Imagine a small piece of grease on a paper towel slowly spreading out over a couple days. I think that's what's happening here. But who knows really for sure. Coinhelp!- I do respect your opinion, we'll just have to agree to disagree on this one.

I most certainly don't want to argue, but discuss! I am a silver dollar specialists and have collected them and submitted silver dollars to PCGS for years. I have learned a lot of things from my experiences. A Peace or Morgan Silver dollar can even be toned in one spot because of a fly spec. It looks like a black dot on the coin, but the rest of the coin is not toned.

I also have an understanding of the minting process and that blanks can have toning before they're struck. I just have a lot of experience with examining toned coins and metallurgy, plus chemistry. I don't think I am a know-it-all but this is toning. Not toning after it left the mint.

I have handled thousands of silver dollars, including Silver Eagles, and I have seen this before. I just wanted to help the OP with his question.

I have studied silver and what this metal reacts with and how it reacts in different environments and substances. I have done well since not one coin has come back from PCGS with artificial toning. I just have a lot of years involved in this very subject.

i once heard something about pcgs being picky about grading certian types of ase's in a 70 because of somekind of wash the mint does on the coins/bullion that causes spotting on the coin afterwards. could be that . ive had a couple that have done the same.
