Thanks for all the encouragement, everyone! (Cherrypickers unite!)
I edited my post with slightly better pics. I'm hopeful it's genuine, but even these better pics are probably not conclusive. It looks good to my untrained eye (though I read with interest the recent topic regarding the added 'S', and this 'S' has the correct serifs.) It was accompanied in the dollar box with some really nice IHC
from 1906-08. It would surprise me if a fake made its way into that batch, but then again it would surprise me to find it at all!
For the past couple years I've kept my eye open hoping someone missed a mintmark on an 08S. (Mine is dented, and needs upgrading). But I never thought I'd find an 09S!
I'm telling you guys, finding tougher D- and S-mint US coins is easier than it should be here in Western Canada. I scored an 11-S and several 31-Ds in small wheat bags recently.
Regarding grade, I think it falls short of EF, but "Liberty" is full and I'd give it VF. No big deal, though, since later IHC
didn't circulate much. Grade doesn't seem to deliver much of a premium.
