Stapling money is against the law

Stapling money money is against Philippine laws. Doing so is equivalent to defacing or mutilating money.

Although arrest or imprisonment of those who do this is not common, there are adverse effects of this behavior that we should keep in mind. When money is defaced or mutilated, the Bangko Sentral ng Pilipinas (BPS) shreds affected bills and replaces them with new ones. In fact, the BSP regularly replaces old or mutilated bills but ruining money on purpose forces the BSP to put out more new bills. This means more cost to the BSP. The same is true for writing on or putting stamp marks on money. Let us keep our money clean. SOURCE:
