Validity of coin grade

I was just want your opinion on this question. If a coin was in certain grade when it was graded, and over the years have developed ugly tone through improper handling such as sun exposure, would the original grade still be valid?

Thanks

Ok first of all, please note this is not in any way an area of expertise for me. That being said, here is my best shot at an answer. I would say that as long as the coin was in the proper type of slab which has not been tampered with, the grade would still be deemed "valid". However the "eye appeal" which is subjective from person to person, though there are strong tendencies in the community, would be deminished to some extent or another. This would mean although the grade itself hasn't suffered the price most likely will have.

 

Gee, that's a hard one! Suppose that your wife, who was slender and beautiful when you married her, became fat and ugly after giving birth to four or five kids. Would you ask her for a divorce?

In most cases yes the grade is still valid but as mentioned it may become harder to sell. In extreme cases it could be enough where the grade should be changed, but there is no standard one size fits all answer to that question.

 

AMEN!!!

 

No.

Even in plastic, coins can sustain damage and will necessarily be down graded.

 

If a gold or silver coin downgrades because of toning while in a holder, you should be compensated under the grading guarantee of the TPG or they may provide free conservation to bring it back (their option, not yours). I don't think copper color is guaranteed, but the numerical grade is.

Holders are not airtight or watertight, so be careful where you store them. Storing in sunlight is a bad idea.

The new PCGS holders are waterproof to an extent.

 

Even if they are waterproof, the plastic they are composed of is differentially permeable to many, many elements. In other words: the elements (such as sulfur) goes right through the molecules of the plastic.

 

Ummmmm........

 

Those who don't remember the past are condemned to repeat it

 

Was it the "fat and ugly" part, or was it the "kids" part that made you ask for a divorce?

 

Not if it is the result of improper storage. That is in their guarantees. Frankly their guarantees are void if the coin deteriorates after slabbing. That's in the guarantee too.

 

Coins not only can change grade but also color as many tone inside slab. Several have even corroded due to chemicals used months after being sealed up. Coin doctors can do amazing things to get coins graded but alot of times its only a temporary fix.

 

Yup, you are right about what the guarantee currently states. A couple of years ago, I heard David Hall speak about PCGS paying out lots of money for coins that changed in the holder, but he must have been speaking about past policies.

Did the sun damage the plastic or the label?

 

No, plastic and label look new and untouched.
