You might not be able to sell it to them, but you could give it to them.

That would fulfill one of your two goals.

My uncle and my cousin have a junk yard, that is a scrap metal business.
For a while 30 years ago my cousin was collecting converters, waiting
for someone who would buy them, to recycle the platinum, to arise. He
showed me a pile of converters, but I don't know what happened after
that.
