Just trash?

[Murph]

Ran accross this on the beach.? My first thought was a large smashed fishing weight but my detector says Siver/copper.? When found it was all one peice then took a hammer to it to see what was inside.? I assume its just some sort of trash but thought I would post a pic here before discarding it.?

test it's weight versus volume to see if it's lead.
