Why don’t Newton’s rings qualify as a Mechanical Error?
Newton’s rings are the natural result of two pieces of plastic coming together. They may be more or less pronounced depending on the thickness of the collectible. The CGC holder is built with long-term preservation in mind, and its construction is necessary to ensure the protection of the encapsulated collectible. Newton’s rings are not an indicator of any deficiencies with the CGC holder and therefore do not qualify as a Mechanical Error. For more information about Newton’s rings, watch the video below."
