Doesn't look like a SMS to me. 1967 was the last year of the die so none have ever been found with FS, even the super mint 68s and 67s by pcgs and ngc don't even have any remnants of even one stair. There is a mark in the stairs but I've seen some FS with equal amounts of markings, Thoughts?
While a nice strike, the big hit would keep it out the FS IMHO. Worth keeping until a better one shows up.
+1 on that, Plus an added thanks to the OP, when I cranked my head to the left my neck popped 4 times. Guess I don't have to go to the chiropractor tomorrow.
Ding Ding !! No not the Ice Cream man, but he did go by yesterday ! A little too early , do you think ? Oh Oh .
