COLOMBIA. Banco de la República de Colombia. 20 Pesos Oro. July 20, 1927. P-378.The highest of the three denominations printed by Thomas de la Rue for this series. Another exquisitely designed face, printed in violet, with allegorical figures and Caldas portrait at left. The back has the common design of the bank headquarters. The type was not in Ward in any format. An exceptional piece and certainly worth in excess of perceived catalog value or trends.
