First time for me to get what I think you call a "dirty roll". It had 38 nice shiny, clean 2010 Shield Pennies and the other 12 coins in the plastic sleeve (BWR) were dirty coins with no Cu pennies in the roll at all. Not even a 1982 penny.
I've been sorting since July, 2008, and have been posting on here since September, 2008 and this was first for me.
Enjoy your coin searches, everyone.
