Ala. Code § 15-13-43

In lieu of a deposit of money, a defendant may deposit negotiable bonds of the United States or of the State of Alabama of the face value of the cash deposit required. Such bonds shall be treated in the same manner as a deposit of money, except that the clerk shall, under order of the court, when occasion arises therefor, sell the said bonds and apply the proceeds of such sale in the manner that a deposit of cash may be required to be applied.
