The last series of the denomination separated in Cz. Miłczak's catalog as a separate variant B45c). It is possible that this is its unlisted variant. Series D in variant c) has, according to the catalog description, both the series and numeral designations of the same height (10 points). Estimating this height on the present banknote, it looks like the height of the series letters is lower than the numerator. This seems analogous to the variant described for the $10 denomination, where the series is 9 pt high and the numerator is 10 pt.
Partial and hardly noticeable longitudinal overdevelopment and a broken lower left corner.
Beautiful, fresh presentation. All-natural with strikingly visible embossing of the printing in the paper.
