Roll Hunting.

that is very true, especially when it comes to half dollars

I think you will find this a lot if you search halves I always look at the obverse first and then I look at the reverse of a coin when I am roll searching. By doing it this way all the coins you put down will have the obverse facing down so when you put them back into the paper roll they will always be the same. The first thing I do when I open a new roll is to look at the way the coins are in the roll. Now you can still find good coins in rolls that have been searched because you never know just what the one before you was looking for. I think you will see this more in rolls of halves then any other rolls.

THE OTHER BRUCE.

Yes when I've dumped rolls out and they all are mostly turned the same way I never find anything worth keeping.

If you get tubes of cents and they are all turned the same direction, then someone may have check them before. But sometimes searchers never put them back in the same direction. I know I do as I always search all coins the same way. Obverse points/reverse points then stack them into small stacks then place them into a tube. I put them in the tube in groups as they are less after to hit each other and ding themselves. Regular circulated coins I toss back into container to re-roll them to put them back to work. Also if any I find that are BU, but spotted/scratched/distracting I toss into the circulated batch as rejects. So the one I put back into rolls have to be very nice coins. That's just how I do it.
