Intercept Shield products are no longer available however the coin supply stores still have left over stock.  So while they may have been available, they are no longer producing this product.  Here is an FAQ from ICG website:

Q?Do you still provide the Intercept Shield Holders?
A.As of right now, we only have Intercept Shield gaskets for:

-Morgan/Peace Dollars

-Half Dollars

-Cent

-Five Cent

-$10 Gold Indian/Liberty

-$5 Gold Indian/Liberty

FYI, I purchased a few of these, and I can say the overall quality is good. 1668Chris appears to have a nice product here, and his communication and shipping times are top notch. Also of note, Piedfort slabbed coins will fit the smaller bags if you only have a little patience. Two 5oz or 12oz slabbed coins will fit into each of the larger bags. As for prospects of increased protection against corrosion, only time will tell.

Thanks for the feedback, much appreciated!!

While the design might seem relatively simple, it definitely has its challenges in production.  However, since I am sort of a perfectionist, I expect no less than 100% consistent quality. This translates into a product that is not only effective and functional, but meets expectations in terms of consistency.

Regarding the effectiveness of Intercept, I uploaded another research article focusing on case studies, whereby companies like Royal Mint of England, Guggenheim, and Raytheon used Intercept to solve their challenges.

thanks again,

This appears to be a nice coin, but take a look at the NGC pics:

http://www.ebay.com/itm/1994-100-Yuan-NGC-PF69UCAM-12-oz-999-Silver-Unicorn-Extremely-Rare-Piece-/200892696833?pt=US_World_Coins&hash=item2ec6234901

It has significant rim scratches, and the toning spot appears to be getting larger and darker and since grading.

How does a coin damaged like this get a PF69 and why doesn't the NGC pics show this damage?  :confused1:

Regarding the rim scratches, I recall reading a couple of years ago that NGC does not consider the rim part of the coin.  I know tha sounds silly, but I have seen a gold 1998 PF 70UC flower tiger with a sizable rim dent.  Regarding the spot, it looks like the coin may have been conserved prior to grading.  On the NGC photos you can see the remnants.  However from the looks of the eBay photo it appears the spot may be below the surface.  In which case the spot will reappear if it comes in contact with harmful gases.

Or the spot appeared after grading, which is not that uncommon.

Maybe it all depends on the grader and the day of the week. There are many slabbed MCC with the designation "Proof Details" "Rim Damage". Coins that have been dropped receive that designation. I can't imagine them grading a rim-dented coin any higher. I have never seen it. If they have graded it hogher, in my opinion, they shouldn't have!

If you look at the listing it doesn't say anything about rim damage or scratches on the coin.  Nor do I see any on the coin.  I'm not sure where the idea is coming that the coin has rim scratches or damage.  The damage mentioned is on the edge of the SLAB and scratches on the slab.  Even the close-up picture of the spot shows a nice scratch that is clearly on the slab since you see the reflection in the coin.  In other words coin is likely fine unless it was damaged while in the slab since the slab appears to have been somewhat mistreated.  Of course the coin still has the spot and possibly haze like many silver mcc's.

Not my listing or coin by the way.

Ahh yea I see what you mean on the date side of the coin.  Does look like some decent scratches.  They don't show up as well on the seller photos so I wonder how noticeable they are.  As far as rims and damage.  PCGS and NGC don't downgrade as much for damage in those areas as they do for other areas where distractions are more obvious.  I made a post sometime ago on that subject.  I'll see if I can dig it up.  Damage on this coin looks pretty decent so a 69 could still have been an over grade if the damage is as obvious as it appears to be on the ngc photos.

The post you mentioned is here:
http://china-mint.info/forum/index.php?topic=4808.msg27607#msg27607
It was in the discussion about Edge Nicks and Grading.  A very good post, and I bookmarked it.
