You probably found the most precise equivalency. Yes, the original article is talking about that kind of thing.
Also I enjoyed @IanMcLoud’s step-through of my list. No each item was not equivalent to the 30,000 artifacts guy. The point was to illustrate that keeping what you pick up is subjective and there are so many variations. They weren’t meant to all be equivalent to each other within the list, or to the 30,000 artifact guy. Just a grab-bag.
If I were out walking in the desert and found an arrowhead, I’d jump in the air and kick my heels together. I have been looking for arrowheads all my life and have never found one. I might keep it, unless there was some well known prohibition on it. But if I were out walking and found 200 arrowheads together in a group… I’d think twice. If I found one of those big pressure-flaked spear-tips, I’d think twice. If I found stuff bigger than, say, what fits in the palm of my hand, I’d think twice and probably not even move it from where it rests, then try to figure out how to report it.
I’m keeping every gold nugget that I find. That’s a personal rule and I’m tattooing it on my arm for reference. I’ve never found any nuggets, but I’ve found small flakes when panning in a frisbee.
@slybevel, I used to live next to a glass dump. But not anymore. Found many an old blue bottle. I also used to live next to an open pit copper mine. Let me tell you… that place was daaaaangerous.
