Some number of Achaemenid Lions (with built in cheating)
There are two known systems of weights and measures from the ancient Middle East. One system was based on a weight called the mina which could be broken down into sixty smaller weights called shekels. These lion weights, however, come from a different system which was based on the heavy mina which weighed about a kilogram. This system was still being used in the Persian period and is thought to have been used for weighing metals.

"Finally, a puzzling item is the lion weight from Abydos in the Dardanelles at the British Museum (BM E.32625). This was indubitably intended as a full talent and has actually a Greek letter alpha for “one” on the back, but in fact it weighs 31,808 g, an approximate 5 percent excess over the theoretical Babylonian standard of 30,240 g. One can only assume that this weight was for checking payments subject to some kind of surcharge. The Aramaic inscription on the weight, reading ʾsprn l-qbl stryʾ zy kspʾ can be interpreted as “correct for (weighing) staters of silver” and suggests that tribute in Athenian silver tetradrachms was being discounted on payment into the Achaemenid treasury, since these were the coins known in the East as “staters.”"
