Anyhow these classic proof sets are kinda dead these days and I'd like to get a set with a non-dog half dollar. I've seen some slabbed pf-67 1942's halves for sale on Heritage and they appear to be normal business strikes. No proof finish. Do I have to buy a PFCA to get a proof-like surface? Why are there only six PFCA's in the NGC pop report and only for 1942? I thought all proof walking halves would have a cameo proof finish?
