Hi John, I recall my Tiawanese veneer buyer bought about 30,000 ft. of Burr Oak @2400/thou U.S., thinking it was White Oak, then had to sell it at 80 cents CDN to a mill after finding out.
When I found a good stand of Swamp White Oak, he wanted nothing to do with it so I left it standing. Some of the trees exceeded 4' dia. I cant tell you how many times I checked my books to verify the species, as to Mossycup, Swamp, Burr, White, Stave, etc. etc.
Burr, however, seems to be quite distinguishable, due to its burry, knotty appearance. An Italian buyer called it Blue Cherry Oak, but never showed the color of his money
