Dollar bills that are damaged by fire are known as mutilated currency. Burned money can be exchanged for its original value if:  

• more than half of the bill can be identified as United States currency or,
• less than half of a bill is present, and the method of mutilation and supporting evidence shows that the missing portions have been totally destroyed. Money in this condition must be mailed to:

1. Regardless of the condition of the currency, do not disturb the fragments any more than is absolutely necessary.
2. If the currency is brittle or inclined to fall apart, pack it carefully in plastic and cotton without disturbing the fragments and place the package in a secure container.
3. If the currency was mutilated in a purse, box, or other container, it should be left in the container to protect the fragments from further damage.
4. If it is absolutely necessary to remove the fragments from the container, send the container along with the currency and any other contents that may have currency fragments attached.
5. If the currency was flat when mutilated, do not roll or fold the notes.
6. If the currency was in a roll when mutilated, do not attempt to unroll or straighten it out.
