Will be easier, just to post what was available
In 1975 and 1976, "S" mint Ike's were issued in
3 coin proof sets that had 40% Ike, JFK and
Washington quarter.
3 coin UNC sets that had 40% Ike, JFK and
Washington quarter6 coin clad proof set, cent through dollar. 1975 has type One Ike
6 coin clad proof set, cent through dollar 1976 has type Two Ike
So if you have a six coin set, it is clad.
For it to be type One, it would be a 1975 clad proof set.
In 1975 set, cent, nickel and dime are dated 1975.
