Other than Gold Connectors

I'm curious what people are doing with their cut connectors that don't go into the gold pile. For example, PS/2, RCA, and power adaptors. Are these going into your dirty brass bucket? I'm required to cut these from the cord at my yard. I think these are brass.

I've accumulated a nice pile of them, and I would hate for it to end up going in the trash. But, I don't see an effective way to extract the brass, and I've not seen any buyers for them.

Please do forgive me if this has already been answered. I've seen plenty of threads on what is a gold connector and what to do with those - but nothing on the other connectors other than pulling out the brass on outlet plugs.
