There is Not an "S" stamped under the loop handle. But it does have slight issues.
Because it is out of the box, there are some slight surface scratches/wear marks on the bottom and handles and one inside on the non-stick surface. It has been handled but has not been used in someone's kitchen.
I believe this was a store display model. A very functional and exceptional non-stick fry pan from All-Clad. It is stamped on the bottom along with the number to ensure authenticity.
