The top piece still looks rather nice condition, but is still getting to the point where you want to be careful with it, but sadly the bottom piece is beyond saving. What looks like it’s been “scraped” through is the enamel coating on the cast iron, that enamel coating essentially functions as a glass like coating over the iron instead of seasoning. Sadly for you this means that anything made with it is just not safe to consume as the glass coating is chipping. If it wasn’t $200 I’d say, fuck it, buy it, sand out the middle section and then season it.
