I recently found what I believe to be an argillite guilford round base, quartzite point, three unusual argillite points with two that are very similar to the points described in the thread on arrowheads.com, "narragansett bay argillite spear point tips" and the other is tri-faced and most likely untyped...also a rhyolite adena blade, quartzite blade and (please don't laugh) a crowfield point made out of slate!! I know it sounds crazy but it has all the characteristics of the shape. I hope to get all my finds authenticated in the future.
Here is a photo of the "crowfield":
