bucket of solder

I found all this solder (long bars and short) hidden in the garage when we did a spring cleaning. I don't need it, and I'm not sure if it's even usable to make weights. No clue on what to ask for it. If you want it and would like to trade something of what you think is equal value, let me know.

Somewhere in the mists of my memory, I'm thinking solder has tin and lead in it.  Maybe left over from sheet-metal work?

Maybe 50/50 tin/lead solder? Looks like retail is $10+/lb, but not sure how easy it is to find a buyer.

I just want to get rid of it. Maybe a plumber would find a use for it.
