Well the verdigris above lincolns head on the rim hurts the coin for me a bit, i would say not enough to give it details but it will hurt who wants it. As for grade i see a bit of wear i am going to say AU50-53. Price wise would say it will mostly like sell on ebay for 7-10 dollars !!
So many 1909-VDB Lincolns were saved (as a "rare" variety) that its price never went anywhere. The 2011 Redbook shows $12 in G-4 and $22 in MS60, a very tight range for a century-old coin.
Do you have an extra S mint mark laying around you could solder on there? NOW how much would you pay? Hey, don't laugh. Many have.
I'm continually surprised at what some of us have been finding with those powerful USB microscopes. I'll bet if he got one of those, he'll find an S.
From the photos, I can't find any wear on the reverse. I can't confirm wear on the obverse, but the cheek is suspect. The worst I would grade it given I can't see the cheek would be AU58. It looks just looks like the poster child for a slider unc.
