Eletric circuit breaker

I have a customer the has a 4'x4' 4' tall bin full of these. I have myself pull ten of them apart. Most of the weigh is plastic, the rest is metal, with some copper, brass, aluminum, and silver contacts. How would you even price out something like that?

Sell them on the bay or marketplace or CL. Make the price worth it for an electrician to pick them up.
