1979 United States Proof Set, 6 Coins Inside!. Original packaging: Identical to that of the 1978 Proof Set, except that the position once occupied by the Eisenhower Dollar is now occupied by the Susan B. Anthony Dollar. Because the new Dollar was smaller in diameter than the old, it was surrounded by a filler ring of clear plastic, making the coin seem to "float" in the holder. The frame and outer packaging also remained the same.
