Longshot, but found these at al old church

[adalabama]

Hunted (with permission) at 160 yr old church today. Didn't stay long but I did find these, in the same hole. My pointer kept picking more up but I was getting tore up by mosquitoes so I left.
1 pic is the front, and the other is the back. I assume its copper because they are green.

Possibly pieces of an old sprinkler the older ones were brass maybe hit by mower.

When you enlarge the 2nd photo, it looks like a piece of cast brass with an ornate design, or possibly a date or number on it. Can you make those details out with a magnifier?

Its very ornate.
