Look what has happened

WWBillman

to my 1976S Eisenhower Dollar. When I made this MS67 about 2 years ago it was blast white. Now it has light gold rim toning with blues and purples in the centers. I think I really like it but wonder why it has toned like this.

dipped/cleaned before being slabbed and not properly neutralized after the dipping/cleaning. and even if properly neutralized this leaves the surfaces of the coin primed and ready for fast retoning. the purple is a telltail sign along with the golden edge tone

<< <i>dipped/cleaned before being slabbed and not properly neutralized >>



michael, I personally broke this out of the silver mint set and submitted it to PCGS for grading. If it was dipped or cleaned it was done at the mint.

michael

then at the mint there was somekind of film on the coin or whatever put there at the mint during one of the processes. and by cracking the coin out of the mint packaging and exposing it to a different set of envirommental circimstances this caused the coin to tone

Isn't that what Proof Big Ugly Heads naturally do? PCGS slabs do not prevent a coin from toning but will slow down the deterioration process.
Funny thing, I have PCGS slabbed silver coins that I dipped 4 years ago and they are still as white as they were when I pulled them from the jar of Jeweluster. My dipped clad don't look so hot though but they are in ANACS slabs so I guess that's totally irrelevant.

LMAO, But it is a silver Mint State business strike not a proof.

What was the slab stored in? Were there other items containing paper, cardboard ect ie sulfur in the same space. Did you use any silica or metal safe in the storage area?

I am quite afraid for my blast white proof Ikes. Any info you could provide could help others in keeping there Ike slabs blast white.

Thanks

never realized that fratt

maybe the coin
even in the holder! toned this way due to being stored in a certain evvironment after slabbing

I keep my coins in safe deposit boxes. Try the NGC slab storage boxes. They hold 20 and are
also compatible with PCGS. I just ordered 3 more directly from NGC. They charged me $13 for 3 boxes
,including shipping. Thats $3.5/box. How can you go wrong?!!!. 1800NGCCOIN. Has anyone else
tried these. I love them.

(P.S: When you call NGC, ask for Mellissa, she's nice)

FrattLaw,

It was in an Eagle certified coin album that was stored in a bed room dresser. I also slabbed the Washington quarter and Kennedy half from the same set and they were just starting to show this kind of toning before I sold them about 6 months ago. I had alot of different coins in that album but those were the only ones that have done this. Now it is stored in a PCGS slab box in my safe.

Really do not know what is causing it but since it has gotten this far I am hoping it will continue with the blues and purples getting brighter.

Ooops, well it's acting like a Proof, Bill.

I just bought a second safe just for slabbed coins. I keep all albums, boxes, proof sets ect in one and only plastic slab boxes with slabs in the other. I also needed the space so it worked out well.

I am leaning towards those Intercept Shield boxes for my slabs, they're just so damn ugly, I can't bring my self to use them.

Littleton sells a corrosion kit you can insert into existing 3 ring-binder sets (pg. 33 of the October 2002 Coin Magazine) that I was thinking of using to line the interior walls of my safe with, or cut a piece of it and put in my PCGS boxes in the upper lid.

Can we say paranoid?

Anyway, I can imagine that if you store your slabs with copper coins, paper, cardboard ect, this will probably hasten the toning process.

I'm no chemist, but I can imagine a environment inside a dresser. Chemicals, soaps, cleaners, solvents ect are used to clean clothing and I'm sure a residual coating is left even after the best rinse. Gases may be released from these. Furthermore, if the dresser was wood, wood I think contains potential damaging chemicals, especially any processed wood, ie pressed wood used for furniture. Furter, if someone used chemical cleaners to clean the dresser, this might have also impacted the coin.

Of course all speculation, but I would suspect that a pcgs box in a safe is better. If you want it to keep to toning, leave it were it was and it probably with continue. But I'm not toning expert. It'll be interesting to see what the toning experts say tomorrow when they read this post.

Can I have your address WWBillman? I'll be sending my white coins along via Registered mail. Just hold onto them for a couple of years, will ya?
I would lean more towards some kind of film left on the coin from the mint, in combination with how the coin is being stored. I'm no chemist though!!!!

I don't know what caused it but at least it's attractive toning. Maybe your Ike caught it from another Ike while waiting to be slabbed.

I have a number of mint fresh coins that I've put in plastic holders and they are taking on that mellowed toning. Your coin is gorgeous and I think eventually it'll add value to it.

I have had this problem and found out I was storing my coins too close to my open bottle of peppermint schnaaps.
