Nice finds,especially the buckles..back in the 70s there was a friend out Orangeburg way..he had some items his dad found near eutaw springs before the dam was built on the Santee..one item was a leather Dragoons helmet with the metal visors and plume attachment intact
I would say that the silver shoe buckle & CSA button made staying up for 2 days straight digging all night in the cold rain worth it! Congrats on all the nice finds!
