This 100 ₸ gold coin is dedicated to King Croesus, the last ruler of Lydia from the Mermnad dynasty, who reigned from 560 to 546 BC. In historical tradition, his name is associated with the early development of coinage and the establishment of a more orderly minting system. Croesus is regarded as one of the first rulers to introduce a consistent approach to controlling metal purity and to use an official symbol of authority on the obverse of the coin. As a result, monetary circulation became more reliable and easier to understand for trade. Issued in .9999 gold and weighing 1.24 g, this proof-quality coin draws attention to an important stage in history, when the coin became not only a means of payment but also a symbol of state guarantee and trust.
