I gave these a quick rub but they do still need cleaning. I found no damage on the porcelains but the lids have surface scuffing. They are somewhat grouped in the photos. The upper 6 in the 1st photo have the same mark. The other pairs of 2 have the same marks but are different than the others. You will see 3 more in the last few photos and they are included as well for a total of 15.
