LinkCopper core is the one which has the interior layer copper and sainless steel on sides. Very well made heavy pans, its fun to cook with them. I have 2 pans in this line in my all clad collection and I always reach for there copper core pans. The 2 qt saute pan is $169 on Amazon and the 2 qt sauce pan is $222. Looks like $99.99 is a very good deal for either one of them. They have other all clads on sale too.
