  • Patent number: 5191972
    Abstract: A device for storage and display of small, generally planar articles such as coins or the like, comprises one or more generally planar compartments for displaying a face of one or more articles. The articles are held in a cavity, preferably a closed, dust-tight cavity, of a generally planar article holder having a pair of opposed walls having the cavity therebetween. The article holder is releasably held in a display compartment by a generally planar retainer member which bears against an article holder which is correctly positioned in the display compartment. The article holder is also prevented from lateral movement in the display compartment and is thus held in an article viewing position in the display compartment whereby an article which is correctly positioned in the article holder is properly positioned in a display compartment and is viewable through an aperture in the retainer and through a transparent wall of the holder.
