Flo is living proof of the G-10 concept, See his latest post " RIVER FINDS 2-21-09".
Also, when your talking " G-10 ", most of us use that designation if we find a whole point but I'm thinking when it comes right down to the professional designation its really tough to get a high rating.
Factors like material , color [ white sun burned ? ]
flaking quality and "design" of that particular style
come into play.
A true G-10 can be found on the surface or under it or underwater or anywhere for that matter. But it's a qualified authenticator who's willing to give it a grade or just a qualified grader, which have started popping up in th last couple of years. I'm not sure how one becomes either, except by experience but I think there are some types of certification programs available that have recently come about. Would make a good article for Texas Cashe magazine though.
in addition to no dings, and i mean absolute zero(tip,ears,base,etc.). for a point to be even considered G10 in must have near perfect symmetry, flawless workmanship, above average material. i have been told i am to picky though.
oh yeah, and for a point to labeled G10+ in simply needs to be the highest quality example known. period!
so yes John you can def. find a G10 artifact on the surface.
this castro is a true G10 surface find by my great uncle in the early 1900's. it was found near Leon Springs, close to where the Dominion Ranch is now in San Antonio, Texas.
you know very few folks have ever seen this point. it makes me wonder just how many other spectacular artifacts are out there, tucked away in an old frame, or shoebox?
