如何兌換損壞的美元?

You can simply go to any banks that provide U.S. currency.

It will be your best interest, if you can choose the bank you usually bank with.

Under federal regulations, banks have the responsibility to exchange that for you, providing that the damaged currency can be still identified and not counterfeit.

Example of banks that are required to exchange - HSBC, Citibank.

銀行与找換店是不會兌換有損壞的紙幣(貼膠紙)，因她們收了卻不能再兌換給別人，只可交回給該損壞紙幣的國家，當中又涉及運費問題，所以她們不收，以免麻煩。若你身邊有親朋去美國，兌換給他們吧。
