Toning in grading service holders

[RobertB]

Out of curiosity.....has anyone ever held a certified coin long enough to see toning set in? Personally, I haven't. I was just wondering if anyone has or ever heard of such an occurrence?

[nwcs]

No, but I do have a PCGS slabbed JFK that had end roll toning on it. The toning has darkened a little in the year+ since I had it slabbed. Other than that, I haven't seen any (even old holders like a 1st gen pcgs) acquire color.

Yes, my 26-D Merc. It's been in several holders actually....it's gotten darker...unfortunately.

I have a SAE in a PCI (older holder) that says 'MS67 100% White' and it is very much golden toned on both sides. I bought it about 6 months ago (already toned) from k6AZ and it has become darker since then. Pretty, too.

 

Here is a link to a picture:

It is a little darker now.

Well, I don't know if they've toned in the holders, or there were a lot of color-blind graders, but I see a lot of MS & PR Red IHCs that in my opinion are solid RBs - not even close to RD, but only 30-50% RD - you see them all the time in the older PCGS holders (& some NGC also) - & that's why you'll see sale prices in say a Heritage Auction of a "RD" IHC that sold for 30% back of bid - 'taint Red - did it tone in the Holder? Don't know - you'd have to have seen it right after it was graded to know.

most all of the time red coins in holders that have changed colors is because of the coin being played with/enhanced/dipped/comserved or what ever nice name you call it then the coin changed in the holder due to these enhancements done to the copper coin before it was submitted

 

of course if the coin has turned in the holder and was totally original since the day it came from the dies the heat of the dies sealed this red color on the indian head coin and for one hundred years or more it has not changed then it supposoedly changes in the holder well something was done to it right before it was sent into the services and over a short period a few weeks to a few years it changes in the holder due to this enhancement right before being submitted

 

another more uncommon scenerio is someone gets a totally original red coin certified and then puts it on a radiator in a house and submits the coin to really drastic temp and humidity changes i do not think anyone would do this purpasely but i guess it is possible!!??

I have seen toning darken with Seated Lib coins in slabs over a long period of time. I suspect that they were dipped to remove dark toning before being slabbed. Then were not rinsed and neutualized properly.

I have 2 or 3 modern commem gold coins that have toned in the holder. When I bought them - clean as a whistle. But today - toning is obvious. And with silver - only one - again a modern commem.

 

BTW - the gold coins are in PCGS slabs - the silver NGC.

Actually silver coins in older NGC slabs, before then put in the gasket between the label and the coin, have indeen toned in the holder. Usually the areas closest to the label develop the toning first and it then slowly seeps down the coin from that area, instead of from around the rim.

 

As for the PCI toned ASE I have also seen other modern commems in PCI holders that have turned a solid gold color even though the slab indicates 100% white.

I know for a fact that PCI holders tone Silver Eagles

I don't believe the holder caused the toning after incapsulation- I think the coin was improperly dipped or treated before and then turned in the holder.

I improperly dipped a few of those and submitted to PCI and ended up wholesaling them out (at silver price plus a dollar or two). Others were submitted that were original blast white and they remained white.

 

Lay blame here on the coin's mishandled treatment prior to grading rather than the holder itself.

Logic would also show that if it was the holder than many many more of these including other white coins would be turning, not just a few select Eagles and such.

I can't make any comments on the PCI holders.(Never left a coin in one long enough to find out)

The older NGC holders will definitely create a gold colored peripheral tone.

Well I may be wrong - but to the best of my knowledge until recently no slab was airtight. And if the slab was not airtight then under certain conditions any coin - dipped, not dipped, properly or improperly - could be subject to toning. It doesn't necessarily have to be caused by the slab itself - although it may be.
