I will side with T-BOP in that the 1967 is a business strike. And the 1968 S is definitely a business strike as there were not any SMS in 1968 that I am aware of. As far as grading goes, as nice as they may seem, I see too many flaws on both of your coins in the way of dings and dents in the focal areas.

Hate to be a "downer" but I'd hate it more if you spent the money for grading only to realize your cost exceeded the value of the coins. I'm no expert, just my
