Six coin set (includes an Susan B. Anthony Proof Dollar coin) where the coins will have DEEP CAMEO contrast. The mint introduced this new more compact style holder in 1979, which resulted in less air getting to the coins resulting in fewer sets with problems. Minor distractions are pretty much limited to Proof haze or rim toning on the coins. All coins in this set bear the more common normal shaped or symmetrically shaped (for lack of a better term) 'S' - Type I mint mark.
