When I say "text on coins", I shall include numerals too, because I am making a distinction between the pictorial and non-pictorial elements of the design.
The English numismatic designer Percy Metcalfe
was famous for the distinctive art deco style that he brought to his designs. He even extended this to the numerals he used. Here is an example on the Bulgarian 100 leva coin of 1934. The numeral 9 in the year 1934 appears particularly angular and stylised.
Here is the reverse of an Iraqi 4 fils coin, dated 1938. On the left-hand side, Metcalfe shows the numerals of the Western calendar year in Arabic style, while on the right-hand side he shows the local cultural version, again in Arabic style, but both are highly stylised, and I have not seen anything similar on the coins of other countries that use Arabic script.
