Telser (1995) and Sumner (1993) argue that the optimal system of denominations of currency would consist of a sequence of denominations that differed from each other by a factor of three. The fact is that today no currency follows the powers-of-three principle. I argue that existing currency systems are the result of an evolution over time that is subject to historical influences and social factors, especially the counting systems that societies use.
