These were most likely used in a restaurant, they are in good to very good condition, there is one that has a divet chip and a visible dark spot. Look closely at all photos for condition details, they do have some light scratching, but it is minimal in my opinion.
They measure 12" long x 8" wide. These types of platters sell individually for around $18- 20 each, so this is a fair and reasonable price for this many in this condition.
Comes from smoke/pet-free storage.
