Interesting fact
One interesting fact about the Nummus - Valentinianus I coin is that it features the first known use of the Roman numeral "V" to represent the number five. This was a new numeral that was introduced during the reign of Emperor Valentinianus I, and it replaced the previous system of using the letter "X" to represent the number ten. This change in numerals can be seen on the coin's reverse side, where the number "V" is clearly visible in the exergue (the lower part of the coin's reverse side). This innovation in numerals was a significant development in the history of mathematics and has had a lasting impact on the way we represent numbers today.
