War Code Letters

Twenty eight different ETO codes were used. Spread across the five lower denominations, they employ twenty different letters. The letters I, O, Q, U, X, and Z were not used. The first four of these are the letters which were always avoided in serial prefixes on the A Series notes, due to their potential similarity to numerals. Perhaps tradition precluded their use as ETO codes also. X and Z could possibly have been allocated, perhaps to the £50 and £100 notes, but never used. It is not known why the codes were used in the order in which they appear, and no pattern to their occurrence is apparent. The code letters were probably chosen at random.

All of the codes are distinctively coloured. The colour tone varies slightly for most of the codes. This is normal, and probably due to variations in the ink supply, the ink itself, or in the force in the press used to print the codes, or a combination of all these factors. For a few of the codes, there is a very significant variation in colour shade. These are the three blue codes (10 Shillings: H; £1: Y; £20 A), which vary from a pale sky blue to a very dark blue. The occurrence of the variation is apparently randomly spread throughout the dates of issue. The difference in shades is most marked in the H code on the Ten Shilling notes. • Version 2.1.0 • Last update • COPYRIGHT ©2000, 2009, 2015, M Mac Devitt. Reproduction with citation permitted.
