So Im pretty sure that it is but I just want others to confirm, plus I dont belive that there was a 1916-s unless you know something that I dont which is a likely possibility.
It is not a 1916. 100% sure, even without the S mint mark (and you're right, there were no 1916-S SLQs).... If it were a 1916: The rivets would be weaker, the fold in the dress under Liberty's right (leftmost) arm would be stronger, and the head of Liberty would be "over" rather than "under" the dot-dot-dash border near the rim. Even on extremely well worn issues like the one you posted, you can look at these three details to attribute the coin as a 1916 or not. Hope this helps...Mike
Note the drapery under the shield. http://imgs.inkfrog.com/pix/coop49/1916-1917_STANDING_LIBERTY_DIFFERENCES_HEAD_SHIELD_001.jpg
Thank you for your repplies, Im without a doubt sure its a 1917-s type1. can anyone guess a value in its current state and is it worth having slabbed?
p.s. another way to attribute these coins is the relative position R in LIBERTY versus the flap of the dress visible above the shield. You can see the variation clearly in the photos in post #4 to this thread. As an aside, the position of lettering against field elements is a very common attribution technique on early issues (say pre-1830), but much less so for modern issues -- this coin being an exception to that rule.
