Not sure about the set your mom is sending you. But I bought a 20pc set back in 1985. And I still use them to this day. These pots, pans, covers have been through a lot in the past 25 years of continues use. They have a solid aluminum bottoms no copper. They heat extremely evenly. Even when use on old coil style burners, you don’t see the heat rings in the bottom of the pan. And they are the only set I use to this day.
Yes they are not as shiny due to a few scratches. But overall appearance they are of a 1 year old stainless set. So they have help up extremely well over the past 25 years.
