These are weights!

These are weights for a scale. These were used by traders, weighing gold, and other valuables like jewellery. Trading in the Iron Age were not done by monetary means. People traded with exchanging goods. Various commodities were traded, including metals, furs, grain, luxury items like gold, and crafted goods like pottery, ceramics, and tools.
