There is a trade-off between small, thick flans and wide, thin flans of the same weight. The wide flans require less energy to strike. The power of the strike flows through a thin piece of metal quite easily. Think of an aluminium wrapper of a tablet of chocolate. The thick flans require less energy to make. The molten metal is rolled to the required thickness. The more often it is rolled and the more energy applied, the thinner the metal.

The minters must have liked the thin flans, but they would have had little influence. Labour was apparently cheaper than energy. That makes sense when there is high unemployment. If one big brute was spent, you could just hire another big brute for the same low price. It is not a recipe for a good life.

Peter, the flans would have been made small and then beaten to make them bigger (wider). THis would need both energies- heat and strength. So to save on both, the mint workers, who were paid on the Kilo / tola weight of coins produced, may have cut corners......

Maybe so, but I think you are underestimating your ancestors. If you hammer the metal to the required thickness, the flans will be slightly uneven. The result will be weak portions and parts of the die not even making it as far as the flan. See the pre-machine coins of Afghanistan and Iran.

Rolling was a known technique that would yield perfectly flat plates of metal and the flans would normally be completely covered by the dies. Rolling was a known technique for centuries. The rolls could be powered by animals or water, but if human energy was used, you would have a point.

It seems to me that the prime motivation for the thick coins was being in a hurry, otherwise known as understaffing. ;)
