How much of a dollar bill can be missing?

Answer 1

According to the U.S. Department of the Treasury's Bureau of Engraving and Printing, a bill is considered mutilated if it is missing more than 50% of its original size. This means that up to half of a dollar bill can be missing and still be considered valid currency. However, in order to exchange a mutilated bill for a new one, more than 50% of the original bill must be present to verify its denomination and authenticity.

Answer 2

More than half must remain for the bill to be exchanged. Half or less renders the note valueless.

Answer 3

If any serial number or number is missing off the bill you need to send it to the federal reserve and wait to be reimbursed for the said bill.
