"What Is It???" Wednesday

Mystery object, you tell us!

This artifact could be found all over the country.  Any guesses?

WHAT IS IT???

Last week seemed to stump the chumps...it's a fragment from a 24 lb cannon ball associated with Carl's on-going dig at the Spanish Quarter (view last week's post for pics).  Given the time period of the strata the fragment came from, could be from Oglethorpe's 1740 siege of St. Augustine!
