I am unable to take a guess at the value of that tooth, but I know it's more than just a few dollars. Collectors also look for the overall size of the tooth, but I have absolutely no experience in shark teeth diving.
I am very interested in it though. I took my family down to Fla for a vacation and we found lots of small ones at Venice beach on the west coast. We also took a guided shark tooth search with a professional guide. We found lots of teeth, but nothing big.
I have been trying to get a couple of my dive buddies interested in going on a road trip to South Carolina to dive the Columbia river, but these guys have no interest in it. So, I'm stuck. I'd like to get down your way to do some tooth dives. Are there any shark tooth dive charters that go out? I'd really be interested.
