Questions for PCGS regarding CORRECT storage of RED COPPER

Since it has come to pass that PCGS is aware of Red Copper turning color in slabs under certain conditions, I will ask you to both provide us with an Officially Approved method of long term storage and also would like you to investigate a more efficent slab design that will maintain the existing color of the coin for the future. Thank You. **please forum members don't respond let's await an OFFICIAL response from PCGS executives on this VERY serious matter**

• Store you copper in a place that has low humidity. That means a constantly air conditioned environment if you live in places like Florida.
• If your copper is in slabs, store it in a place where the temperatures of constant. Avoid taking copper coins in slabs from places that are extremely hot to places that are extremely cold and vice versa. This will help to prevent moisture from condensating inside the slab.
• Don’t store you copper (or any coins for that matter) in a closed space with materials that contain a lot of sulfur, like rubber bans.
• Many copper collectors like cloth coin envelope liners for storing their copper, but I’ve found that some of these devices promote toning and tarnish. Cloth liners are okay for brown copper, but I’d avoid them for pieces with red surfaces.

<< <i>Before everyone freaks out, yes copper will turn, especially depending on what it was exposed to BEFORE it got into plastic. I sat in a 5 story beach front Condo in Puerto Rico with my Lincoln set in Slabs in Eagle brand notebook holders for 4 years. They were stored in my open bedroom closet, were mold permeated my clothes. Twice a year I had to pull the dresser from the wall and wipe it down with Clorox to get rid of the mold. The chrome rings on the binders even rusted. BUT NOT ONE COIN TURNED. Nor have they 3 years later since I moved to SC . So before everyone freaks out about their copper turning. Your memory will give out in most cases before you can even detect it. Unless of course the coin was exposed or doctored with some chemicals before it was slabbed.

That's the real issue my friend. Once doctored, the surfaces are now chemically active at the molecular level, no matter how well they were rinsed. Encasement in a plastic slab just slows oxygen infiltration. That's why coin doctors do their mischief just prior to a major coin show. This way they or their proxies can get overnight grading well before the coin will manifest tell tale signs of "enhancement." From what I've seen, red copper/bronze will always give away the enhancement within a year if in a slab. If not slabbed, it will divulge its secret within a few months, maybe much sooner.
What does PCGS mean by not guaranteeing the color? Does that mean they will still guarantee the grade? How will a coin showing a surface like the biblical Joseph's coat of many colors not show a major diminution of grade?

All good points, IMO. I would add another...
• Store your coins in something that limits airflow around the slab, with lots of dessicant (and check it often).
Would you care to chime in, Sir?

Sadly people freak out because they have to pay huge premiums for the red color. I refuse to pay those prices, and stay away from red copper except for modern (coins that are 60 years old or newer) material.
