Can't tell.  So far they're all unmarked.  

You're not concerned about the tolerance and re-centering issues?
You think the cookie will fit back on the hub precisely enough
that it'll be aligned with where tracks were before?

For some crazy packrat reason, I too also have a couple hundred
Amiga-era floppies that failed in duplication at my software business.  
Maybe I was looking for a brand-related failure pattern back then, too.
