Intro price for 50 bags is less than $1 a bag shipped.
I just bought some myself. Will see how they work.

Thanks, Chris. Very interesting products.
Question on your product description "Expected Corrosion Protection Term: 5 Years" - Do these bags need to be replaced every 5 years? Also, 5 years from the date of manufacture or purchase? Is expiration date indicated on the bags or somewhere?
Thanks in advance for clarification.

The life expectancy of Corrosion Intercept is from the manufacture date.  Unfortunately there is no born on date on the bag, however, the manufacturer has to continuosly source new product for the use in the Electronics, Military, Auto Parts industry.  So new Intercept material is being produced continuously.

The actual life of Corrosion Intercept depends upon the environment the coins are stored in.  The key here is that Corrosion Intercept is copper in color.  As the bag absorbs harmful gases the copper color will turn black.  When this happens it is time to replace the bag.  So it could be more or less than 5 years depending on storage conditions and the levels of exposure to harmful gases.  As an example, I have had samples for about 2 years, and not seen any change is color.  While the bag is working, it has not become saturated enought with harmful gases to change color.

Hope this helps.

Rather than bagging each individual slab it would be nice to have a way to bag my slab holder boxes. Anything like this available?

I have added a few excellent research bulletins and presentations discussing Corrosion Intercept.  If you have a few minutes, I encourage you to read thru them:

Currently there are no plans to create a bag large enough to hold slab boxes.

thanks,

Are the coin storage bags intended primarily to prevent corrosion and/or toning of silver coins? Will they help prevent copper and carbon spotting on gold coins? Is there in any value to storing platinum or palladium in these (I have never personally seen toning on these metals)?

Toning and corrosion are used interchangeably, since toning is corrosion.  So the answer to your question is yes.  There is a lot of information and research on the website regarding the benefits of Corrosion Intercept.

Spots on gold coins result from impurities in the coin that are concentrated during the minting process.  Two most common impurities are silver and copper.   My understanding is that when corrosive gases corrode the silver and copper, the form spots, so yes Corrosion Intercept should help prevent copper spot from forming or reforming after conservation.

I am not aware of any corrosion issues with platinum or palladium, but at .65/bag, it a small price for protection vs. no protection.

If you put an intercept bag on a slab will it still fit in a Ngc box
Any plans on making big bags for the Ngc boxes

I just tested the NGC boxes.  Its a little tight, but it will fit. You have to place it in slowly to avoid the bag from tearing.

Regarding larger bags for NGC boxes.  I originally answered this question no a couple of posts ago.  While there are no plans to make a custom size bag for an NGC box, we should have in stock very soon larger bags designed for graded comics (9 1/2 x 13 3/4).  These should fit one maybe two NGC boxes.  I will check when the bags arrive.

The large bags for comic books have arrived and they will fit one NGC 20 slab box.
