  • Patent number: 5133450
    Abstract: A snap-type holder is described for collecting baseball, basketball, football, or other type sports cards. The holder includes a clear plastic bottom plate having a recess just slightly larger than the card to be placed therein, so as to correlate with card manufacturing tolerances. A clear plastic top plate snaps tight over the bottom plate by a pressure fit resulting from clearance specifications of 0.001-0.002" so as to seal the card against moisture, dirt and ambient air, and so as to secure the holder if it were accidentally dropped, thereby protecting the sports card from damage. A notch is provided in the holder to allow separation of the top and bottom plates when it is desired to remove the card for replacement.
