K. Gorman,
The reason certain Dune's chips sell below face is because these are the chips that were buried in concrete. They came to light when construction workers were building the "Oasis" extension that carried the Dunes entrance to the street. Many were purchased by one individual. All of the "golf scene" series are common and sell for less than face. If you purchase any be sure the cement has been properly removed.<g> Best, Jim
