Whenever it is necessary to convert any investment, as provided for in Section 133.02 into cash, it shall be done by first offering the obligations held by the City to the Sinking Fund Commission and, if the Commission declines to take the same or any part thereof, then the remaining obligations shall be sold in any manner provided by law for the sale of investments by the Sinking Fund; provided, that no obligations shall be sold for less than par and accrued interest.
