The problem with card holders

[Archive]

Hello

I was talking to a close friend who works to preserve paper related items. I showed her a card in a psa container. She said that some plastics can damage cards because they give off a gas. The process is called "off gassing". I do not know if these containers do this. This is just a heads up for collectors.

Some plastics have PVC's which over time will damage paper. The most inert plastic, and the safest, is mylar.

When a card is placed in a thin sleeve before being slabbed, that sleeve is mylar. But I would hope each grading company uses plastics that are safe.

The last couple of cards I broke out of PSA holders had the card laying atop the sleeve, not IN the sleeve. The last SGC holder I broke had no sleeve at all. Maybe those guys should use the sleeves to preserve the card.

What a world it will be one day if all of the slabbed cards are deemed tampered with because of the chemicals transferred while confined in plastic....

The U.S. gov't allows a certain % of plastic "leeching" in food and drink packaging too. Bottled water is one big culprit. Next time you run your blacklight over a card to check for counterfeiting/altering, run it over yourself and see if you fluoresce too!

Leave it to you to notice

Raymond: Okay, just take off those pants now, I'll work the hamstring.

George: Oh, the hamstring's fine.

Raymond: But you wrote that it was tender.

George: I wrote. Pfft, I wrote.
