Coin Roll Hunting

Lately I've been reading through some interesting threads over at the Coin Community Forums.  Of particular interest is a thread where people post their finds from hunting through rolls of half dollars.  Seems like people consistently find silver among halves, so I'm going to take a crack at it.  I am planning on heading to the bank this week to try and order my first $500 box of half dollars, hopefully I'll be posting some good finds of my own!
