These were consigned to me by a very reputable artifact dealer. However, he could not guarantee 100% the authentications. He said he was about 80% sure they were all authentic. Not enough to list as authentic, therefore, we will list as modern. They are all great looking arrowheads ! You be the judge, LOW starting bids. S/H is $5.99 for as many as you wish to purchase. There will be no more at these prices so ride the train on some great looking items ! S/H will be combined on multiple wins. $5.99 for one or more wins.
