Administrator MattM CS Posted December 5, 2023 Administrator Share Posted December 5, 2023 Hello! Thank you for contacting us. The natural effect you are seeing is referred to as a Newton Ring. They are present in all of our encapsulated books and are considered normal and acceptable. This is a result of the inner well (which holds the book) or the Mylar sheet over the book contacting the hard-plastic outer shell; these plastic parts have different refractive indexes that sometimes create a rainbow effect when they come into contact. The effect may be more or less pronounced depending on the thickness of the collectible, and can both diminish or increase over time. The CGC holder is built with long-term preservation in mind, and its construction is necessary to ensure the protection of the encapsulated collectible, including the Mylar sheets over the book, which has been approved by the Library of Congress for the preservation of paper. There is no liquid present or anything that can damage the book. Newton’s rings are not an indicator of any deficiencies with the CGC holder and therefore do not qualify as Mechanical Errors. We have a video that details the effect that can be viewed HERE. Reholder service is available, however, there is no guarantee that reholdering will eliminate or diminish the presence of Newton Rings. The fee is $20 for books valued up to $1,000, and $50 for anything valued above $1,000. Please note, that the grade assigned to the book should not change unless any damage occurred post-encapsulation, in which case the grade will be adjusted accordingly. To qualify, the book must still be encapsulated in its original CGC holder. If you have any other questions, please let us know. Thank you!
