Another good gag is in the Tarbell Course. It is only a paragraph long. It is using a roll of bills. If you only want a few bills, several rows of the bills can be left long and connected. Then roll them and put a rubber band around them. Pull them out to pay for a meal. Tell the casher to cut off how much she needs.

Another use is if you have a cut-no-cut scissors. Pull out the string of bill and have some cut off 2 or 3 dollars. Comedy gag at its best.

Don't know why but during WW2 people believed $2 bills were unlucky, so no one wanted to keep them.

Isn't that the gimmicked version? You could make one, but the Mismade Bill really begs to be examined. Some of the impact of the effect comes from the examination.
