What do rpg-lionessies love? This question was asked by generations of philosophers and sages, and many-minded old freethinkers. And now the answer has been found! What Sumerian lionessy doesn't love chests filled to the brim with silver shekels? It is in such chests that silver-slit treasures await the lionessy in the dark corners of the black black dark creepy dungeons.
Why are gold coins in all (most) rpg games, but in this game they are silver? The answer lies on the surface. In ancient Mesopotamia (the Near East, where the Sumerian civilization was located), ordinary "commoners" often did not see gold in their eyes. They were still lucky if they had a chance to hold silver in their hands. Moreover, for the amount of gold that is given in many RPGs for one dagger or an unsightly ax, in those days it was possible to buy a city, if not a whole country. So silver looks much more appropriate and historically reliable as in-game money.
Why shekels and not just coins? In ancient Mesopotamia, for many centuries, such a currency was in use. It meant simply a measure of the weight of silver (about 11g.). The very word "she-ke-l" comes from the Akkadian root "weigh". Later, such a silver coin and word spread to Carthage, Tire and Ancient Israel. In the latter, it has even survived to this day. Unfortunately, however, it is no longer in silver form. So the lionesses in their travels have yet to "loot" more than one talent of silver shekels.
P.S. Yes, they are square, not round!
