All these are from northeast Maryland. None larger than about 2.5".
The first one APPEARS to be made of bad grade of obsidian. There are volcanic outflows within a mile or so of where it was found, but these were ancient volcanos. Obsidian has been found here but not often. Semi transparent on some edges. We get more rhyolite and granites here. ID? The second is a black flint.
Grey point might be a Brewerton Corner notch. Maybe of Onondaga chert, which is sometimes found here. The one on the right the hard to find Newark Jasper, my first of that material, although I have been to the little park there in Newark, Delaware. Not sure what kind it is though. These mines have been worked since paleo times. Thanks.
