1974 S Silver Clad (1,306,579 p)
As do the other silver dollars in this series, this second-lowest mintage Ike proof Contains .3161 oz pure silver, some of these may have been made in 1975, as public law 93-541 (Dec. 26, 1974) authorized coins made in 1975 to carry the 1974 date. The mint was apparently concerned about people hoarding 1975-dated coins as the bicentennial approached.

No Silver Proof Ike Dollars were minted with 1975 on the obverse.
