no 2011's yet... Not too long and the boxes of dimes pennies and nickels will be loaded with them... I don't know about quarters because I don't do those. Half dollars, I don't think will show up 2011's for a year or so when people dump mint bags...
I haven't seen any, I don't think I've even come across the 2010's yet. I'm sure if you find them early enough they will be worth putting on e-bay though.
