What about the pocket weight of carrying around 10 or 20 dollars in one dollar bills as opposed to 10 or 20 $1 COINS?
Yeah pants pocket will weare out much faster!
First off; if you are carrying more than 5 in your pocket then that is your own fault. Right now you are willing to carry at least 3 quarters in your pocket if you break a dollar.
Second; people will carry insane things in their pockets. Like I stated in a post above this one, I have found at least 8 quarters in a pocket spill. I have found that many on a few occasions. This tells me that people do not have a problem carrying that many medium sized coins in their pockets.
