Wire Plug Ends - worth keeping?

After days of perusing this forum I am overwhelmed with the info.

Have a specific question.
Is it worth keeping some of the wire end plugs that you cut off to keep 'clean' insulated wire.

Back in my storage auction days I tossed those in with metal.
Someone should have told me that the big power supplies have a transformer inside. Oh well...

Anyway. I recall some time the last few days that the ends of data cables have gold plating and have a value?



Which if any wire plug ends are worth keeping?

TIA

I don't cut any plugs off cause my yard gives the same price with plugs or without, they're not very strict with wiring. I used to cut the gold plated ends off and sell those to ewasted but now it's not worth it since I get more for wire then I do for the gold plugs.

Thanks guys.
I know I probably looked a little lazy after I posted this.
Somehow the forum shows the similar threads after posting a new one.
I even tried deleting the thread, but could not find out hos. Probably need some more reading there, too.
I have in the past turned in clean wire and wire with plugs separate, but got the same price.
I thought they made a mistake and did not ask. I probably should.
The e-waste buyer in towns wants it separated, but I don't sell those to him, since his prices are way lower than the other place.
So far I had almost completely just appliance cords, power cords ends etc. Have not done much computer wires.
I definitely won;t waste my time removing the brass ends. Seems not worth my time.
Thanks for the input though.
Much appreciated.

Flybacks can go in with my motors here I only put in a few at a time though...

My yard used to take fly backs as motors but now they only take them as dirty aluminum.
