The following procedures should be used when packing mutilated currency for examination and possible replacement by the Bureau of Engraving and Printing:

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.

7. If coin or any other metal is mixed with the currency, carefully remove it. Any fused, melted, or otherwise mutilated coins should be sent to the:

Superintendent U. S. Mint Post Office Box 400 Philadelphia, PA. 19105 for evaluation.

For cases that are expected to take longer than 4 weeks to process, the Bureau of Engraving and Printing will issue a written confirmation of receipt.
