That's quite a list. You should have no problem getting #3 or #4. Item numbers 1, 5, 6, 7, 9, 10 are occasionally found but will pricey. #2 ... the one Dean acquired (dug locally here near Gettysburg) was the only one we ever saw. #8 ... this was in Dean's collection also, an odd variation, so cannot guess if there are other specimens available.
