3.遙想當年紅色政權第五次反圍剿人力物力維艱,紅軍幣發行照樣設有防偽共同暗記。

For modern Chinese gold and silver PCGS slab cause coins to tone faster and make them very unattractive.  Maybe the airtight holders trap the contamination and destroy coins quicker than if the holder allowed the coins to breathe.

Thanks for the interesting info.

I've only submitted coins and medals to NGC because I don't want to pay for membership to more than 1 grading firm and NGC has, in my view, done a good job for me.

The 1 thing that PCGS may currently have going better than NGC (but that will likely change) is PCGS's virtually air tight holders. For preservation over the long term, this seems to be a big plus.....though I do wonder how long the actual plastic of the holders remains viable before it starts to decay, crack, and disintegrate.

Aren't PCGS's slabs supposed to the more problematic ones or have they introduced better quality slabs? Just asking for clarification.

Grading companies aren't perfect, even NGC and PCGS make many mistakes, however, in almost all cases they stand by their mistake and refund you the market value of the coin. 

Back in 2009-2011 PCGS was slabbing many counterfeit 2000 1oz silver mirror coins and imperial coins, their graders didn't know what to look for and worse it was taking 2-3 months to get coins graded because they were so short staffed.  In 2011 they arbitrarily decided the maximum coverage for PCGS holder Chinese coins were limited to $1000, while their expensive secure plus service which was $45/coin the guaranty was unlimited.  That was the turning point when PCGS coins went from trading at 10% premium to NGC to years laters NGC trading at 10% premium to PCGS.  Today I believe PCGS is back to unlimited guarantee on all PCGS coins, but for 1-2 years it was dicey. 

NGC mistakes have been less harmful, confusing 1992 LD for SD or vice versa for 5-7 years.  I had 50+ slabs incorrectly labeled and it took years for them to fix.  Overall NGC is 9 out 10 in my book, while PCGS is 6 out 10.  I think most collectors and dealers agree that NGC provides a better product with lower price and quick turnaround.

Modern Chinese Medals / Re: Great Wall 1984 3.3 oz. Silver Medal - Two Versions

I was suprised that Spink Auction listed GBCA graded coin in its auction. GBCA has been known to grade many highly questionable Imperial and Republic coins and has a very bad reputation inside China. IMO, Spink should refund you the cost to protect its reputation. For any reputable auction house, refund for a counterfeit coin should not have time limit. Have you ask NGC to return the GBCA holder? This may become critical for you to receive the refund.

It was known that matte version Great Wall medal had counterfeit. They shown up in market place in earlier 2010, in double sealed package without box.   

If it's true that GBCA is or has done that, is the reason because their authenticators/graders are 3rd rate sub par or is it because they don't care if the items that go in their slabs may not actually be genuine?

Between NGC and PCGS, does either company have a better track record of being able to better evaluate for authenticity Chinese coins and medals?

Warning.  I purchased Lot #2420 at the Spink's auction in Hong Kong in August of 2018.  This lot included four medals, with a GBCA graded Great Wall silver medal (type 1)(satin finish)(68 grade).  I sent this medal to NCS and NGC for minimal conservation, authentication, grading and encapsulation.  Today, I received the results.  QUESTIONABLE AUTHENTICITY.  Ouch!  My money is lost.  I made a mistake.  I looked at it carefully during the preview in Hong Kong and still made a mistake.  Hopefully, you will learn from my warning and not make a similar mistake.
