The one Scott found? You mean the Georgia plate.
It more likely that the lead was melted out of the plates to make bullets with. The south was so short on supplies that any item that was still usable would have been put into service. Confederates often used eagle buttons to replace missing ones on their uniforms and would have worn the buckles if they needed to.That is a Great find. Possibly a captured plate and rendered unable for service. There was a story about this where a pit was dug here years ago and many US Plates were found in this pit with the hooks and lead all melted out of the backs of the plates. This pit was found behind Confetrit lines and the thought was that these plates were taken from prisoners and rendered useless.
Well, what was left of it. I can see him down on his knees picking each piece out of the fire pit.
