NGC 1943-D cent corroded in holder

I pulled my top 40 box out of the safe today and was shocked to see that of my 3 MS67 steel cents (p,s,and d) in NCC holders, the D has become horribly corroded and the other 2 are fine. I live if Florida so the room temp is pretty constant as well as the humidity with the ac running most of the time. Do I have any recourse with NGC and can someone explain what happened? This happened in the last year, probably sooner.

It depends on when it was slabbed. They guarantee copper for 10 years and I assume this would go into that category. Regardless, call NGC.

 

Any photos, I kind of want to see how that coin looks

 

NGC Customer Service: 800-642-2646

 

Not that I have done that much business with them, but the couple of time I have called, their customer service has been absolutely top notch.

 

Yep, it's the best in the business!

I will call today.

 

hope these pics post correctly, I'm all thumbs

 

I agree with the others that you should call them. I suspect, however, that they will argue that the coin has become corroded because it was improperly stored in a humid environment, and thus, the guarantee does not cover it.

 

All of the TPGs have a similar clause for improper storage.

 

Man, that sucks. Pretty sure they're going to tell you that you shouldn't have chosen to live in FL...

 

Just spoke to Becky at NGC, she has to check further since steel cents seem to have been overlooked in their policy about this problem. It was slabbed in 2004 so the 10 years have run out but she was very nice and promised to get back to me today. Thanks for the help.

 

Please let us know how you make out with this issue.

 

To solve further issues, I would like to talk about where you store them. You say AC is running most of the time, that means sometimes there is very humid FL air in the area. Due to where you live, I would pay extra attention to having dessicant and "sacrificial silver" in with your coins. I have dessicant packs I dry out periodically. Also, though, I put brand new ASEs unprotected in the box. These are my canaries. I figure they will be the first to tone being newly minted pure silver. If I ever open the box and these show toning, I know there is a problem. I refresh the dessicant, I put the toned ASE's away and get new ones, and recheck more often until I am sure the moisture is gone.

Its just what I do to help prevent such issues.

 

What do you use for dessicant?

 

My type set 1943 LWC also went bad like that.
Problem is that zinc is highly subject to corrosion.

I agree that this will be their probable response.

 

The 10 year guarantee deadline applies only to copper and has no application to a zinc plated steel coin.

 

A shame your coins got damaged,best get a dessicant unit for your collection.

 

It might be worth your while to contact Weimar White, a retired chemist who has investigated the effects of improper storage. In several emails he's told me what he uses in storing his coins. His address is weimar_white@outlook.com
