My heirs would probably throw them in the trash, or sell them for maybe 50 cents a piece in bulk. It would be too much work for them to do some research and find out what they are worth.
Ear buds are all they know.
I also have a decent collection of fishing gear. None of my relatives know which end the hooks go on.
They will be much more interested in the gun safe and ammo pile.
Doesn't matter. My will says it all gets sold at auction and proceeds go to two specific charities.
