1 Birr

Pick 46 spans over a decade of issue, during which printing responsibility was shared between Thomas De La Rue and Giesecke & Devrient — an arrangement that produced measurable differences in ink saturation and paper feel between print runs, though both printers worked from the same approved design. Collectors who assemble sets by printer origin find the attribution frustrating, as the notes carry no visible printer's imprint to distinguish them.

The 1 Birr denomination has historically seen the heaviest circulation of the Ethiopian series, and surviving examples from the early 1997 printings frequently show accelerated wear along the horizontal fold lines.
