APCGS, Who Has Used Them And Your Results

Sap claims PCCB uses an inferior plastic. Coinsaus claims they are the same quality. Does anybody have any reference to an independent scientific research document that either supports or refutes their viewpoints?
On a related note does anyone know who manufactures the slabs for PCGS (also NGC and ANACS)and do MSDS and manufacturers specification sheets exist? (Who supplies the raw resin that gets put into the injection moulds?)
China isn't unknown for lax quality control issues (melamine in milk, poisonous dog treats). I'd hate to think that the same country that made drywall (gyprock to Aussies)that oozes toxic formaldehyde might have slabs that will ooze toxins as badly as PVC coin albums ooze goo over the decades. Might save $10/slab and in 20 years you will find your collection ruined.

I wonder if my Boddybagged coins come back as MS coinsaus would buy them as they would have come from such a reputable TPG as APCGS

To put apcgs in the same category as nnc and other tier 5 grading companies would be a complete joke. By the way they are setting up and expanding their company they would have to be at least a tier 3 company and if they keep branching out to expanding they would have to be knocking on the door to being a tier 2 grading company in the future

http://www.madehow.com/Volume-2/Acr...Plastic.html does the first paragragh from my link look like coinsaus post on the bottom of page 8 , at least coinsaus is good at copy and pasting

So by asking for conclusive evidence that the Chinese knockoff slabs are not inferior to PCGS slabs I'm not posting on facts or relevance?
Sap demonstrated that the concerns may have merit by specifying that APCGS slabs are made in China (and the Chinese supplier has a less than glowing reputation), plus nobody who supports APCGS has demonstrated that they are equal to US made slabs or use the same resin. Collectors are naturally concerned about slab quality and you don't see the problem?
Are you intentionally trying to obfuscate the issue?

No, I'm not trying to obfuscate the issue (Nice word there!). I have quoted your post, because it is a relevant question. Thus, the initial comment "exactly this". "

Please note - I am neither a supporter or non supporter of this mob. I am trying to ascertain the value of slabbing. With Sap posting a link which provides evidence that Americans are actually breaking coins out of slabs, I'm starting to wonder if it's actually worth it in the first place.

I think it would be a good idea for representatives(sales, perhaps) from both organisations to post in this thread.
It also makes me wonder about the quality of the capsules advertised on E-Bay, so any research you do will be most informative.
And we know if you're doing the research, it will be very thorough!

Thanks sfitzernator.
I have started making enquiries and officially the big 3 keep it a secret who supplies them (so don't count on a reply from them). So need some loose lips to talk. I'm hoping that as they slab coins same day at certain coin shows the cartons that the slabs come in will have details (like Made in China or even an address like PO Box 103 Anna, Ohio).
The various capsules and slabs do vary in price. A generic brand slab is offered by an American dealer for $1.75 retail, so what with retail mark-up and costs along the supply chain the slab must cost well under a dollar to make.
I put some slabs side by side and there certainly is a difference in the quality of PCGS and NGC slabs over a generic slab (NNC). Differences in finish, blemishes, optical quality (the NNC slabs reflect light like a pastel rainbow).
There have been a few posts on various forums and sites questioning the suitability of current slabs (PCGS as well) for long term coin preservation. Scott A. Travers has raised this issue online (respected dealer and former NGC grader). The slabs are not guaranteed to be airtight and even if they were they don't seal them with the air inside purged by inert gas.Scott posted that NGC ran an aging acceleration experiment on their slabs and the results were disappointing.
They (PCGS) also need to improve their slabbing technique as I have seen a hair inside one slab and a flake of dandruff in another. A blast of clean low humidity gas could blow that sort of contaminant off as a routine precaution prior to slabbing (I was a lab tech for a decade and have seen plenty of set ups to keep things clean).
None of the slabbers is perfect but they do vary in their imperfections.
