They used a lot of different processes and techniques to mint these. There are about nine major types and probably dozens of subtypes.
The ugliest are 1966 quarters that look like they were struck by worn polished dies with polished planchets. They're very shiny and look like slugs.
My favorite are a sort of matte finish that appear to have been struck twice and are probably technically proofs. These are very scarce and may be a subtype that was simply struck twice.
I've never methodically studied the SMS but it would make an interesting project. The cameo versions are often very highly PL.
