That is not true. You can read the patent here and find that they state that the card is not touching either inner surface.
In the context of a baseball card, the item recesses 22 might be provided with peripheral ridges 26 which define a rectangular area into which an object, having the dimensions of a sports memorabilia card, would be inserted. The peripheral ridges 26 would then function to retain the card against lateral movement even when the memorabilia product is manipulated and/or shaken. Further, the peripheral ridges 26 are molded with a thickness dimension slightly greater than the thickness dimension of a conventional sports memorabilia card. As the front and rear portions of the housing brought into contact with one another, the item recesses 22 and peripheral rails 26 define a volume within which the item is enclosed, without either housing portion contacting the item or otherwise applying pressure to item so as to deform or degrade it.
