Those are all normal circulated Eisenhower dollar coins. They were issued by the US Mint from 1971 through 1978 and are in fact not silver dollars (except for some proofs). They are clad and are worth $1 each unless you can get somebody to pay more for them.
Wellcome. Usually you can check the edge of the coin to see the copper clad under the nickel clad. usually if the edge is silver and no sign of copper the coin is 40% silver on S mint Ike dollars coins. Your coins look like common circulated Ike dollars, retail about two dollars each. Hope this helps.
Nice Ike’s. That was a series that helped infuse this young mans love of coin collecting back in the day. I might suggest.... An Ike set is a fairly easy set to assemble. And once assembled is an awesome display piece. You have a good start there. Why not get yourself an album and start yourself a set?
