There’s a lot of stuff like that. In computer science, unexpected program errors are called “bugs” because the very first unexpected program error was due to a moth getting into the punch card system of an early computer.
QWERTY layouts persist in keyboards because they were copying typewriters. Typewriters were QWERTY to reduce the risk of colliding typebars by making common letters distant from each other, an intentional inefficiency.
Until 2001, US stocks were priced in dollars and sixteenth fractions, because the US stock system was based on the 1600s Spanish system, which used pieces of eight (1/8ths of a doubloon).
Why is it 81?
Because of barleycorns.
