There are no employees being paid to roll, there are giant machines that automatically roll coins and I'm certain these are further automated with automatic packaging. You paint a picture of a process that's extremely labor-intensive and I don't think this is true. I recall an ad for a position at Dunbar as a Coin Logistics/Handler that paid $9.00 an hour. If they get some dumb stooge to sit there all day, manage coins, what the hell do they care if they swap any? Usually, what matters is the totals at the end of the day. There is not someone watching the security camera 24/7, especially in the coin area. They'd go out of business if they invested all this into monitoring some lowly coin handler... PLUS is it likely a supervisor would give a hoot if they knew someone was collecting silver? Probably not. IF they were bills, this would be a different story. Coins not much risk if someone swaps one, if their totals off they fire them. Really people, use common sense, although culling probably is unlikely--- It's not impossible.
