Float Copper, Pet. Wood, Others...Looking for value

Jugglerguy I have no deeper insight than what has been shared other than anecdotally - I think the farther west you go - with CA being right in the middle between two prolific pet wood areas AZ and OR - a big piece of wood like that really does become a yard rock as the others have said, pretty commonly. My brother in Redding collects logs and rounds and uses them as landscape displays in his back yard mostly - but what he is generally looking for is quality over quantity. My best advice would be for the gentleman to take the time (and expense) to have the top of the log cut (and polished) the potential value could/would increase exponentially ... or it could crumble which from the looks of it might happen in my opinion.

The rest of it, with the exception of the copper, is common stuff I would expect to see in the 50 cents a pound range. Plain black obsidian is virtually worthless unless he has stellar varieties of rainbow or other sheens mixed in.
