Parks around Atlanta where you’re most likely to kick up some wild Civil War artifacts?

EDITED: I have no desire to remove anything - simply current parks with playgrounds or ballfields that you might find, like I did, old bricks and iron when I went chasing a lost soccer ball my kid kicked down the hill and into a creek.

OP:
I've know Atlanta has done very little to preserve Civil War battlefields or history, but I've found My Top Parks for CW in ATL might be the best places to explore the woodlines or creekbeds to find old Civil War era artifacts.
