I work at a bank in Cincinnati and I always set these aside for customers. At one point I had almost $1,000 in small face bills. Nothing too special but some people ask for them and they are simple enough to separate. About once a year I will find a small note bill from the 30's. By far the most commons would be the $20s and $100s but the least common is the $5. I also include BARR dollars in this as well. I get about 5 or 6 a year when counting money.
