You don't specify if these are double density or high density. But as translucent floppies either were not out there or popular until high density, they are likely high density.
If they are HD, then they aren't worth hardly a thing. High density 3.5" disks are in more abundance than probably any other floppy ever made.
Now if they are double density, they are of use to old Mac collectors (where the oldest macs had 400K single sided double desnity and 800k dual sided double density drives), and Amigas. Probably Atari ST, and other classic computers that used double density 3.5" disks.
