Some artifacts really look like just plain rocks but some can be very significant, from an archaeological standpoint. Here is a very large flake or preform from Stokes County. I saw it at the local Antique Store. They had this stone priced at $175 but 50% off, so they wanted about $90 for it. There was another rock in that collection, but I should have took a picture of it too. It really looked natural, the material was a metasandstone/quartzite. It was shaped like a small baseball bat (a handheld club maybe?) and it was smooth all over. That one was $50. Also, I saw an exceptional Dalton for $135 and an exceptional Hardaway for $195. They had celts, chipped axes, grooved axes, game stones, grinding stones and small mill stones for sale there too. I have see many collections around here and if I posted some pictures of what they had displayed, some here would definitely see one that is assumed to be natural. You really have to hunt in NC to see what I'm talking about. Yea you guys can say I'm a rookie on here but I hunt with experience. I find stones all the time and make use of them. Heck, I make tomhawks and sell them like crazy. I am a Macguyver myself. I've even gave one I made to my buddy for nothing. At first, I thought these tomahawks were going to be dead soldiers, but with some time and patience they actually sell better than the true artifacts I have. All together, some people know what they want for their collection, whether it's natural or not. Yes, artifacts have value to a collector but then there are some buyers that know they're collecting something unique and buy it. I never mislead anyone. One rock I posted here a while back, I was told it was natural here. I had a buyer on it for $25 so I let him have it. He thought it was a grinding stone so I feel like the customer is always right. With all this said, this all depends on what you want to collect. If your area has a lot of debris, then I should have no right to tell them they can't collect it. I just tell them nice finds and say that they're in the right spot to find something better.
