Uncirculated Memorial

Are all 1968-S cents proof?

I am trying to make a complete set of Lincoln memorial cents and was wondering if there are uncirculated and proof types of 1968-s and all the “s” mint marks through 1974-s

Yes, there are 1968-S- 1974-S circulation coinage as well as the Proofs for those years.
