Jeton
Counting tokens shifted across a ruled table to add in Roman numerals, before pen-and-paper arithmetic took over Europe.
From the Middle Ages into the 1600s, European merchants and treasurers reckoned with jetons — coin-like discs placed on a table scored with lines, exactly like the pebbles of the Salamis Tablet. Nuremberg became the manufacturing centre; the workshop of Hans Krauwinckel struck them by the million. The English word counter for a shop's table comes from this reckoning board, and Exchequer from the chequered cloth that served as one.
Jeton reckoning died out when Hindu-Arabic numerals and written calculation — algorism — won. Place-value digits let you work on paper and keep the intermediate steps, something the line board never could. The jetons survived only as gaming chips.
