A display case is provided for displaying collectible items such as photographs, trading cards, stamps or coins. The display case includes a compartment for holding the collectible and a magnifying lens for viewing the details of at least one side of the collectible. An opening is provided in the compartment to allow the insertion of the collectible. The collectible is sealed in the compartment by a seal. By sealing the collectible within the compartment of such a display case, the collectible is not only protected from physical damage, it is also protected from exposure to moisture, air and any airborne contaminants. The magnifying lens permits the details of the collectible to be viewed without fear of damage to the collectible as may occur with physical handling. The seal may be either temporary or permanent. A temporary seal is useful where a collector desires to display different collectibles in a single display case at different times. A permanent seal is useful for permanently sealing an authenticated collectible within the compartment to discourage any tampering with the collectible as such tampering would require that the display case be broken apart. A valve can also be provided either to evacuate air from the compartment by a vacuum source or to purge air from the compartment by the use of an inert gas such as nitrogen. |
