If both the pledged debt and the debt secured by the pledge become due and the pledgee has not collected their right, they may collect from the pledged debt the amount due thereto and return the remainder to the pledger, provided that the amount due to them and the pledged debt are of the same genus; otherwise, they may request the sale of the pledged debt or its acquisition at its value to satisfy their right.
