For whatver reason I have been skunked on all the most recent years of halves. I haven't even found a 2008D, let alone any 2009, 2010 or 2011. I get about 1 other NIFC half each box though. Seems the 2011s are beginning to pop up here and there as folks are buying them and then dumping part of their purchase.
Yes, I got one a few weeks ago and posted here, why are they still making these coins when nobody uses them anymore. Looks like a major waste of money making these coins.
They only sell them to collectors (at greater than face value and production cost), not for general circulation, so the mint makes money making halves.
