Terminal toning - considered damage?

Hey guys/gals,

When toning on a coin goes terminal (black) is it considered damage at that point? This coin has great toning, but unfortunately has this very black spot. What do you think?

Looks like there was a hole in the 2x2 mylar. Personally, I consider black very bad on silver.

While it's technically not considered damage it is very undesireable and grade limiting.

Regardless of how the spot got there, getting rid of it will be extremely challenging and more than likely result in really goofing the coin up from an originality standpoint.

Perhaps NGC's NCS could help?

 

I think this is good advice. I've never had any luck treating a black spot like that. NCS is probably your best option if the coin is worth it. I would be surprised if it could be fully removed, however.

I would say a spot like that is always a negative. Whether it can be removed will depend on the toning. If its glossy black then chances are good it can be removed with minimum harm to the coin. If its matte, or flat chalky, black, then it will most likely be hiding surface corrosion. In that case its best to remove it, but the coin will forever be damaged. I would remove it either way, since the glossy black can turn into matte black.

People think dipping was always done to make a coin white. The truth is a lot of it was done to coins like this to remove black spots and the like, to help conserve the coin. Dipping was not all bad.

So if something like this was sent in , as-is, for grading. Will they still grade it or is there a chance it will be body bagged as damaged?

 

It would be considered eviormental damage IMO.

 

It's a shame, because she is pretty. I was asking because I am thinking of purchasing this coin.

 

My guess is there's surface damage under it and that a TPG would BB the coin.

If it's worth grading then all the more reason to use NCS/NGC.

I would run the other way. It's a problem coin. But if you can be happy with it and the price is right, go for it!
Lance.

 

Well the price will never be right now that the words "problem coin" are going around in my head. If I buy it, I would be angry with it whenever I looked at it.

I'll put the money toward a problem free coin. Thanks for all the input, dudes.

 

For the collector with a moderate mind about marketable toning/corrosion, this would be beyond terminal as far as acceptable "toning" and into the "non-marketable corrosion". Any removal ( even by professional restorers) most likely will involve silver dips and expose underlying corrosion. This point can re preserved by proper storage, so only buy if this state or a dipped/ expected corrosion state is acceptable.
