A small change revolution. Weight systems and the emergence of the first Pan-European money, 2300 to 800 BC.


Metal trade in Europe increases in the course of the Bronze Age.


Systematic fragmentation of metal objects increases in the course of the Bronze Age.


The spread of weighing technology is correlated to the spread of fragmentation.


Cosine Quantogram Analysis and Monte Carlo simulations show that metal fragments comply with weight systems.


Metal fragments were likely used as money.
