(Internal #S410-11). This is a nice, 1-1/2" long, genuine GREAT WHITE SHARK TOOTH (Carcharodon carcharias). The serrations are like a steak knife; tooth is snowy white. This is a PERFECT TOOTH. NEW PURCHASE AS OF 8/22/09, this is the last known, single, legal, largest collection in the United States. We have acquired this one-time collection of 647 in its entirety (all sizes), so when they're gone, they're gone. Purchased from an East Coast c...ollector who has been in the shark tooth business for 35 years. Prices are based on size and perfection of each tooth. Every collection we buy is higher priced than the last because most large collections have already been sold off to individuals. We are the well-known sellers of the World Record size 2-3/4" great white shark tooth from a previous collection. We can wire it in gold or silver as a pendant at no charge, please advise by email after purchase. This is exactly the tooth you would receive, as in all our auctions. Authentication card included. Tooth came from an 18-20 foot great white shark caught before 12/98. No shipping outside the U.S. for this item, due to C.I.T.E.S. restrictions. Click on our Ebay store tag for all sizes! TEETH ARE MEASURED FROM THE BOTTOM POINT, ALONG THE LONGEST SIDE, TO THE TOP OF THE ROOT. That is the standard measurement in the shark tooth industry.
