Did you know CGC recommends you get their slabs be cracked open and re-slab bed every 7 years? Is this true? I was told it's because the gas they use in the slabs deteriorate every 7 years

The slabs are not gas tight so that doesn't sound right. Also they use Argon in gas stored items and Argon does not deteriorate.

They recommend reholdering books after 7 years because that's how long the microchamber paper is effective.

I've cracked open many old label books, some in excess of 15 years in the slab. The microchamber paper was always fine, still fresh looking. I think it is silly to reholder every 7 years.

Thanks for the heads up :)

 

I had heard the rumor too but always figured if that it was an obvious rumor, it would be advertised more often if it were true

But looking fresh doesn't mean that it is fresh. Just ask Martha Stewart.

 

It could still lose its efficacy.

I asked CGC this a couple months ago. They replied that the new cases have a different inner well (material) that you do not need to replace them. A couple books that did have MCP I did re-holder..not all of them though.

I'm reminded of this great ad from Amway. It involved a product they use for detergent that apparently keeps PH down.It was called Basic H. It was pretty expensive stuff at about $22.00 a gallon. They then had a section on lowering the PH of your garden. They recommended that you buy the stuff and just pour it on the ground.

 

I thought that was some of the best Chutzpah I've ever seen in advertising. Somehow, I was reminded of this story. I haven't thought about it in years.

  • Is it necessary to get my CGC book reholdered every 10 (or 7, or 12, etc.) years?
  • No. The CGC holder is designed for long-term preservation and provides superior protection for your books. A properly handled and stored CGC-certified book can last for generations.

    The CGC holder is made from high-quality materials and is entirely archival-safe. The inner well that holds books, for example, is comprised of PETG, a plastic that is well known to be archival-safe and extremely clear. This PETG well is placed inside of a durable outer case that is sonically welded to ensure a secure, tamper-evident seal.

    Many comic books, particularly vintage ones, naturally release ("off gas") acidic molecules over time. The CGC holder is therefore designed to not have an air-tight seal, which would otherwise trap these acidic molecules. 

    For added long-term preservation, CGC inserts MicroChamber® paper into vintage books prior to encapsulation. This MicroChamber paper helps to neutralize the natural acidity of some books by using a specialized, proprietary “zeolite” that was designed to absorb and hold the molecules known to damage archival collections. That is why MicroChamber paper is used by many of the world’s most respected museums and institutions, including the Smithsonian Institution, the Getty Conservation Institute, the Louvre, the British Museum and the Northeast Document Conservation Center. 

    When CGC was first established in 2000, we thoroughly researched and implemented the best practices in archival preservation. We took a conservative approach and suggested that customers may wish to consider reholdering their books after approximately seven to ten years so that the MicroChamber paper could be replaced. 

    Today, however, we have the benefit of having graded 4.1 million books over a 17-year period. This is an incredibly large sample size that represents books of all eras, paper types, paper qualities, storage conditions and grades. CGC and its customers now have ample evidence that demonstrates it is not necessary to have your CGC books reholdered simply to replace the MicroChamber paper. CGC’s archival-safe holder, with its combination of features that includes air permeability, MicroChamber paper and a secure, sonic seal, has been shown to provide superior long-term protection for the millions of books that have been encapsulated by CGC. 

    We have never seen a properly stored CGC-certified comic book that needed to be reholdered for archival reasons. Nonetheless, there are still a number of benefits to utilizing CGC’s reholder service, including the crystal-clear display, enhanced aesthetic and durable construction of CGC’s new holder. 

    It is important to remember that proper storage is essential to preserving your books, and collectors should take steps to minimize exposure to heat, humidity, vibration and light. CGC recommends that CGC-certified books be stored in a dark, dry, cool, temperature-controlled location.

    CGC's holders have withstood the test of time and over the last 17 years have been shown to provide outstanding long-term protection and preservation. No other comic book grading services can make that claim.
