PANAMA. Banco Central de Emision de la Republica de Panama. 1 Balboa, 1941. P-22s. Specimen. PMG Choice Extremely Fine 45. Annotation of "green changed by chemicals". The undertint of this note is blue and green, whereas it should be all green. This was changed chemically, giving a neat two-tone appearance to the note. This was done intentionally, as denoted by the printer. This was most likely done as a color trial, to decide between continuing with blue or green undertint. PMG comments "Printers Annotations". From the Ellicott Collection.
