The best of your lot (the Hologram), was listed on US Audiomart, at $650 and took 57 days to sell (last year).
A Tesla T3, for $375, sold there in two days (this month).
A Tesla T2, for $260, took 146 (2015).
Good luck getting more*, though: much depends on the lengths (not mentioned) in your possession.
*especially: in one lot
Regarding lengths: longer costs more, but: less people (typically) need the extra length.
Synergistic used active shielding, beginning before 2000, with their MPCs and extra wiring, but: have since moved on to shielding technologies that don't require any of that. Long and short: NO, nothing extra special about the Teslas, though as I said, they are still great (at least: better than average) cables. Particularly, at what they can be had for, used.
Don't mean to rain on your parade, but: facts are facts.
