Older David Halloran pot calls

[cannonball]

Does anyone know the current going price for the older David Halloran calls that he hand turned on a lathe? These were stamped Hand Crafted By David Halloran on the back. I have a Crystal Mistress, Twisted Sister and a Birdseye Maple Aluminum all made between 2011-2012. I was also wanting to know what year he went to using a CNC machine instead of a lathe.
