1978 S Copper-Nickel Clad (3,127,781 p) This final coin in the Eisenhower Dollar series was included in proof sets that year. It is the last of the "big dollars", with a diameter of 38.1 mm, this size unchanged since the liberty seated dollars of 1840. As with all the Ike Proofs, these coins tend to be well-struck with excellent detail.
