Went out today to pick up a few sets for my books. Picked up a 79 proof set for 10$ not even thinking about types I and II. Got home and started looking at it and I am 85% sure its a type II set! Including the
SBA. I dont have anything to magnify the mint marks for pictures bit none ofbthe Ss were blobs. I could make out the S pretty clearly on all of the coins. Is there any other way of identifying these types besides the mint mark?
