Claim 3

A numismatic case as defined in claim 1, wherein said frame is provided interiorly thereof with means for holding a disk in a viewing position therein, said means being radially yieldable for adjustment to disks of varying diameters.

Claim 4

A numismatic case as defined in claim 2, said holding means comprising a plurality of resilient fingers spiralling inwardly from the inner periphery of said annular periphery and resiliently engageable with the periphery of the disk in said chamber with a centering action.

Claim 5

Claim 6

A numismatic case as defined in claim 1, said cap having an annular bead raised above the surface of said window portion to protect it from abrasive contact with an external object.

Claim 7

A numismatic case as defined in claim 5, said bead being of arched radial cross section so as to define an internal groove; said frame having a radially projecting seal lip received in said groove so as to seal said cover to said frame.

Claim 8
