.. I understand that banks and casinos pull more conterfiet notes out of circulation than any other place, and the casinos pull more than banks. People fear getting caught less if they slip a few in play than laying them on a counter in front of a bank teller. (so I am told is the reason casinos get so many)

My question is how many do they pull out of the softcount rooms? (ballpark figures)
Also, do many other denominations than $100's show up?

Thanks
