USCIS specifies that the filing fee for processing
the Form N-565, Application for Replacement Naturalization/Citizenship Document, is $555. You will have to pay the exact amount of $555, because USCIS will reject your application if you paid less or more money for filing the form.
Note that besides the filing fee, you may need to pay the biometrics fee, which is exactly $85. But you should only pay the biometrics fee if USCIS requested you to do so. You will be notified whether you need to pay for biometrics appointment shortly after you submitted the form.
