That material is certainly from PA...........I find that color Quartz down towards Lancaster County. It is kind of Yellowish but definitely PA artifacts. Those piece would fetch alot more than $10 each. I would price the Jasper Adena at $25, the stemmed blade that looks like another Adena, I would price at $35, the Quartz Celt would be worth a minimum of $25.....The large Slate Blade would be a $50+ piece depending on size. The Quartz Triangle, which to me looks like it is a Early Triangle, not Clovis but definitely Early Archaic. It almost looks like a Levanna Triangle but if the owner knows to look for the ground base they might find that it is ground. They are found quite frequently around these areas. That piece alone is worth $30+. This is my opinion and based off pictures. It really comes to size for prices. Since i have been dealing here in Pa. for a while I think I have an idea of there worth. I agree with the field grade to some of those pieces, but the others cannot be overlooked. If I saw that frame up for sale I would not pay more than $80 for it. Sell them individually you will maximize the profit on them. I'll post pictures of a Early Quartz Triangle found in Lancaster. Just got to dig it out..................GTP.......
