With all the talk of slabbing in order to preserve a coin, I thought I'd ask a dumb question, as someone who has never purchased a certified coin:
Are ANACS new slabs in particular (and other TPGs in general) watertight? I assume they are airtight, right?
Thanks

Without testing them myself, I understand that most of the top TPG slabs are NOT waterproof nor airtight although looking at my PCGS and old ANACS slabs, they look pretty tight to me. I don't know about the new ANACS slabs. I believe some lower tiered slabbing companies make the claim to be both waterproof and airtight, but again, I wouldn't want to test them. I think the best approach would be to presume that an encapsulation is not waterproof nor airtight, then take precautions based on this. My major concern is fire and none of the slabs claim to be fireproof, so I keep my most valuable coins in a small portable Sentry vault which is supposed to protect its contents for a minimum of 30 minutes in a 1700F (I think) degree fire. Anybody have their coins go through a recent hurricane? Fred |

I would have to guess they are not waterproof.I was able to slightly open an NGC slab by just inserting my thumb nail.

Hmmm, now I'm confused. How can the top TPG cos. guarantee their 69's will remain 69's if air and moisture can reach the coin? |

I just read NCG's statement on their slabs and they say their slabs are NOT 100% airtight and the recommend you store them in a temperature controlled low humidity environment such as a safe or a safety deposit box. Even so, there's so little air in a slab that it probably take most of your lifetime to see any discoloration.I believe ICG uses some kind of chemical in their slabs to prolong the beauty of the coin.

The TPG's don't cover copper coins in their guarentee, so I'm assuming that the amount of air moisture will only be enough to affect copper coins. |

All I can say is that I hope no one on this forum has to find out the hard way if the TPG slabs are waterproof.  |

as a matter of fact I have a 1878 MS-64 VAM-81 soaking as I type this in the sink, it is in a NGC slab and as of 20 minutes there is no water in the slab as of yet. I want to add I am cracking this one out any way so its no big deal
