Sealed Slabs
Sealed slabs refer to collectible items, such as stamps, that have been authenticated and graded by a professional organization, then sealed in a tamper-evident case for protection and preservation. These slabs typically include a label indicating the item's grade, authenticity, and other relevant information. The process of sealing these items provides an added layer of security and ensures that their condition remains stable over time. This allows collectors to have confidence in the authenticity and quality of the items they are purchasing and adds value to the collectible. Sealed slabs are highly sought after by serious collectors, as they provide a level of assurance and protection that is not available with unslabbed items.
