Here a easy one J J most likely knows this one. Is it Bu ? http://www.cointalk.com/threads/20-14-ngc-or-pcgs-graded-coins.240617/
I think it's KM#613 also. Hard to tell if it's copper or Brass(KM#613a) Strange thing is it weights 7.02g, and supposed to be 6.3-6.93g. Seems too dark to be toned brass. Actual color is almost Chocolate Brown. This is closer.
How about this one? One of my dad's friends picked this up for melt. Guess how much it sold for? Sorry for the small pics.
