What is a type M? >>

This was the original proof only version used on the 1968 S. It is distinctive enough to be picked up from pictures or even by touch while blindfolded.

For many years now, I have been fascinated by the many varieties of the early 1965-1974 quarters. I count 6 different circulation strike versions. They are rather minor and probably only a specialist would love them.

Yet there are also 2 proof only versions introduced in 1968 with the resumption of proof production. These are sufficiently differerent to be readily identifiable from pictures and even by touch. Incidently 3 of the circulation strike versions show up on a very few 1968 S proofs. This makes 5 versions for the 1968 S. These same 5 varieties ended up on the 1969 D quarters.

Type M (for modified) was created from a ordinary circulation strike hub by considerable touching up. It was used for the majority of 1968 S strikes. It also showed up on a minority 1969 D, 1970 D and 1970 plain and on a majority of the D mint quarters in the 1970 Mint Set.

You will find more information on this subject and pictures on two previous threads.
