A.  If the issuing bodies deem it to their best financial interest to sell the certificates at public sale, then all certificates issued by authority of this Chapter shall be advertised for sale on sealed bids, and the advertisements shall be published at least one time in a newspaper published in the subdivision of the issuing body, or if there be none, in a newspaper published in the parish in which the subdivision is situated, or if there be none, then in a newspaper published in an adjoining parish and posted in three public places in the subdivision or parish of the issuing body, seven clear days before the date fixed for the reception of bids.  Notice of the sale shall also be published one time at least seven clear days preceding the date fixed for the reception of bids in a newspaper of general circulation in a city of this state having a population of not less than twenty thousand according to the last federal census.  The governing body may reject any and all bids.

B.  If the certificates are not sold pursuant to such advertisement, they may be sold by the governing body at private sale, within thirty days after the date advertised for the reception of sealed bids, but no private sale shall be made at a price less than the highest bid which had been received.  If not so sold, the certificates shall be readvertised in the manner herein prescribed.
