First, a mass of coins in a sock is a dangerous weapon, in the right hands.

Second, I was once in line behind a woman with a huge purse. Of course they stopped the after xray line right on the rollers to resolve her purse while my stuff was still in the machine. It was a pain, but I got a good show. By the time she had emptied her purse of coins that had been dropped in over time and settled to the bottom, she had filled one of those almost white plastic bowls nearly level full with coins. Now what? Of course they run the purse back through without the coins, but everything had already been dumped out and there was nothing there except what one might expect to find in a purse. So empty purse and loose stuff in gray bin was run back through. Sort of makes sense as there could be something in the lining of the purse.

What got me was they ran the bowl of coins through as well. What did they expect to see?????
