This might explain difference in cost between the two. The 2.0 nut is used and the copper is new. Note the copper one has elongated hole.

I believe the elongated center in the copper nut is done to provide a self locking feature. Regular locknuts cannot work in the high heat exhaust area as the nylon ring in the locknut doesn't hold properly, but the deformed copper will.
