Some of it might not be lead. If you want the best price I would go through the bucket. Check everything with a magnet, then check everything with some wire cutters, if you can easily cut into the metal, then it's lead. If the metal is not magnetic, and you can't easily cut into it, then it's zinc. Your best bet, once it's sorted, would be to check ebay and/or craigslist and try to sell the lead to someone who makes bullets or fishing weights, then you can get more than scrap value, scrap value may only be 20-30 cents a pound for wheel weights.
