thanks for looking 
the larger pieces were from various places, including a buried trash area, but the small pieces (probably 5-7mm in diam) came out of one hole in my grandmother's backyard, 8-10 inches down, and the whole area was active during the Revolutionary War (about 7 miles outside of Boston). If not, what could it be?
TIA,
Lara
