I don't know what happened

Doesn't manila paper often have a high sulfur content?
That would certainly tone a copper coin -- and quickly.

If I had sent this in and they slabbed it would this still have possibly happened?

 

Yes. The chemicals they used to turn the coin red may have not been completely rinsed off the coin. They reacted with the virgin metal that was exposed and gave you the result you see. This can happen in less than a year.

Even if the chemicals are properly removed, the virgin metal left after the dipping is very vulnerable to turning brown. It’s more delicate that the original mint surface that’s on the coin when it is struck.

This is why I advise people to buy red copper in old certification holders. If something bad is going to happen, the chances are high that would have happened between the time the coin was slabbed an now.

As a general policy, I stay away from red copper, especially on old coins that are expensive. Buying it is not worth the risk, and the grading services won’t support you if things go wrong. NGC has reached the point where they won’t guarantee a copper coin beyond ten years. Before that time goes by, you have to have the coin re-certified.

 

What is a "certification holder"?

I did not know they guaranteed it at all.

 

A slab. If you get a red coin in an early generation holder and it is still red, it is probably stable and will remain red a long time.

 

Coins should never contact paper unless there is absolutely no other materials.Check this listing of chemicals in various papers.

And the manufacturers usually get the source material from Asian companies who do not specify which are in what, as they only intend its use as Paper and not storage materials for metallic objects.

from the looks I would say it was dipped in Lye to make it all nice and shiny again, but was not rinsed completly afterwards.. letting the remaining lye do that damage over time.

 

A person's coin environment makes a big difference. I do not see how collectors in the SE states, Fla. Ga, Tenn, etc or the NW, Wash.Ore,Ida,etc could keep any coin in any holder from reacting over time, except in in lab situation. IMO Jim

Yes, I live in a desert

 

...and you're a gem.

 

Yea I would never seal my coins. I like to actually see them occasionally. I don't really like slabs for that reason but, sometimes it's just best.

 

Yeah. Give Abe some love ❤️. Try go fund me @bruthajoe

 

9ball gave me a slabbed coin. That’s all I need.

 

Hey. Don’t jump over the side of the boat yet. Ever hear (I’ve learned a valuable lesson). So plan on learning many more lessons. We all count on each other to share mistakes knowledge

 

I guess yes. Sooner than later

 

Things ain't that bad. Yet. Thanks though. lol
