i am an archaeologist, so i thought i might give you a little more info on what you got, just from looking at them. I am not completely familiar with
east coast archaeology, but i have done a little work there in the past. so...
what you generally have there are probably Archaic Period (6,000 BC -
1,000 BC ), and are usually characterized by their stems and side notching at the base of the points. The larger stemmed ones are not actually arrow
heads, but more likely spear points that were used in conjunction with an atlatl, as that Native Americans do not adopt bow and arrow technology until
a littler later in the Woodland Period. The smaller points and the pottery most likely date to the Woodland Period (1,000 BC -1300 AD).
Pottery isn't adopted by Native Americans on the east coast until generally around the end of the Late Archaic into the Early Woodland. The smaller
points are most likely arrow points, since they are much smaller. Pottery also signals the change is subsistence patterns from hunting and gathering
to a more sedentary way of life, and the introduction of agriculture.
check out this book, it has lots of stuff about your area.
