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. In my opinion it would not benefit you to have these graded. It would cost more than what they are worth. 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 Two Cents
worth (no pun intended......lol). WELCOME TO THE FORUM!!!
