Are DEC TK50/TK70 tapes worth hanging onto?

[Thomas Dzubin]

OK, I have a fairly large collection of VAX 4000 and VAXStation 3000
systems which I have fun with and use with both OpenVMS and OpenBSD
over the years....

But, I also have two big rubbermade containers (about half a cubic
meter) filled with TK50 and TK70 tapes which I have never used.

Some are blank, some are the boot & install media for VMS 5.5, some are
software installations, etc. etc.

In the past 25 years that I have had them, I have not once ever used
my TK50 or TK70 drives...I've always either booted off the attached
disks or netbooted.

Should I just throw these things out?   Do any collectors consider them
to be valuable?   Since it's now 2016 and I think the last TK tapes were
made in the 1990s, I'm getting the urge to toss them.

Opinions?  Comments?
