Yep, apparently there's a law somewhere that dictates that no living president can be depicted on a coin. Per the story above:
After Washington, the presidents honored this year will be John Adams, Thomas Jefferson and James Madison. The program is scheduled to run into 2016. A president must have been dead at least two years to appear on a coin.
Frankly, I find this rule to be the silliest I've ever heard. Not that the presidend has to be dead - but that he has to be dead for *two years*. What, is this for fear of a dead president suddenly returning to life, digging himself out of his tomb, and suddenly developing an ego because "Now I've got a coin with my face on it, ooooOOOOOooooo! Now, MUST...FIND...BRAINS!"
Because clearly, that president would be a zombie. And there's nothing worse than a zombie president on a massive ego trip. Thank goodness our government was smart enough to pass this law ahead of time!
Edit: Oops, ya'll are right - those are *dollars*, not *quarters*.
