Just saw this slab on ebay...counterfeit? Something's just not right... http://www.ebay.com/itm/1909-s-vdb-...75?pt=Coins_US_Individual&hash=item43bb9fa557
Sure they did: I cant see anything wrong with OP slab, plus not sure someone would fake a F15 slabbed coin.
It does look "off" to me too. The font doesn't seem right, but I'm probably just not familiar with that generation holder. Looks to match the ha.com auction so that's a good sign.
I know its the coin that is collectable, not the slab. Just saying that it makes more sense to see higher grade fake coins in fake slabs. Maybe at least VF or XF, to make the effort worthwhile.
