Coupon bonds issued by any municipal corporation having a population of twenty thousand inhabitants, according to the last federal census, may also be registered as to interest, and the bonds surrendered and interest made payable only to the registered holder of the bonds.  For that purpose the financial officer of the parish or municipal corporation shall detach and cancel the coupon and shall endorse a statement on the bonds that the coupon sheet issued therewith has been surrendered by the holder and the coupons cancelled by him; that annual or semi-annual interest shall thereafter be paid to the registered holder, or order by draft, check, or warrant drawn payable at the place of payment specified in the bond.  Bonds registered under this Section may, with the consent of the municipal corporation or parish and the holders of the bonds, be reverted into coupon bonds at the expense of the holders, and again converted into registered bonds from time to time as the governing authority of the municipal corporation or parish and the holders of the bonds may determine.  The parishes and municipal corporations are authorized to pass all resolutions and ordinances necessary to give effect to these provisions.
