If they used the good ones. If they have the magnetic oxide coated with mylar (or somesuch) rather than it being the surface material that can flake off. If that’s the case, and they don’t get used very often and being stored in a cool, dry place, the disks could well last another 50 years.
Run the degausser over ‘em a time or two and they’ll be good as new! Blank, but good as new...
