Six coin set (includes an Eisenhower Proof Dollar coin) where the coins will generally have DEEP CAMEO contrast and may have just a touch of Proof haze toning as is usually found on older Proof sets from the mid to late-1970's. Often these black box Proof Sets of the late-70's will have Proof Cents with minor distraction usually some light carbon flecking due to the fact that the plastic holders were usually poorly constructed allowing air to tone the coins over time.
