Put a couple of UV lamps in the coils and hook up a HV power supply, and you have a nice bug zapper!

Or put it in a plexi box and wire up a zip cord and lamp socket for a table lamp! !)
Maybe you could use the coils for an antenna match box? Being air core coils, you won't saturate the core and burn it up...
As to value, what ever anyone would offer, and I would go $5 max at a swap n shop...
