  • Patent number: 5133451
    Abstract: An improved container for the storage, display and protection of collectable items such as graded coins, stamps, jewels and other valuables is disclosed. Display of the collectable items is enhanced by an optical element which provides reflective means for viewing the item indirectly. A reflecting prismatic ring is preferred to provide viewing of the periphery of a cavity or the collectable item enclosed therein. In a second embodiment where two or more components may completely enclose the cavity, various tamper-resistant and tamper-evidencing features are further incorporated in the container design to discourage and prevent fraudulent substitutions of collectable items, modification of grade and value certificates enclosed therewith, or counterfeiting of container components.
