This is a disaster in the making. Expect copper toxicity if cooking in copper. It happens more often than you think.
You know nothing about this obviously.

The 12 piece set is $4200. You were probably too poor growing up to ever learn anything about this is my guess. But to reduce your anxiety, I'll point out that the cooking surface is tinned.
Even if the internal surface is tin, it will easily thin out when on the stovetop, resulting in the food coming in contact with copper, leaking much copper into the food. Tin is also not okay with acidic foods either, again thinning out and bringing the copper into contact with food. I guess money doesn't teach even an iota of common sense.
In short, it is not worth even $42. If you're making a museum at home with your utensils, you're solving no one's problem, not even your own.
