Question On NIFCs And Clad Proofs

I'm going to order my first box in a couple of weeks. I was wondering if both NIFCs and clad proofs have copper rims or not.

Thanks to all who post,

if i'm not mistaken, you'll see copper on every coin including S proofs beyond 1970 - unless its a silver S mint proof, and in that case you'll see they resemble what a silver clad 65-70 looks like.
