This is lohis wife. Great find!!! I don't think your find is worthless. If it is infact an authentic Pooka Shell and not a replica, I was told they are an extinct shell found off the coast of Hawii and the one I have is quite vaulable. The shape of the shell is a great clue. What they call a raw shell has not been modified or filed down. The center is sunk in and it has a lip around the edge. You have a beautiful piece as far as I am concerned. Good luck on future hunts...
Hey Paul R....nice find and Congrat's,Still have my first set of Pooka's from the late 70's.Maybe "lohi's" right,check into it,you never know..Great find and HH!!
Don't think that you have to find something under your coil to call it treasure!! MDing is just a small part of treasure hunting.
Keep your eyes open for all kinds of stuff! don't be afraid to bend over a dumpster, or hit a garage sale with a vengeance.
Treasure is where you find it.
Dano.
