The earliest Korean coins were minted and circulated for about one hundred years, from about the 990s to around 1105. Based on [[Tang Dynasty]] [[Chinese currency]], the coins were imprinted with terms including ''Haedong'' ("[[Sea of Japan|East Sea]]"), ''Samhan'' ("[[Three Kingdoms (Korea)|Three Kingdoms]]"), and ''Dongguk'' ("Eastern Kingdom"). | The earliest Korean coins were minted and circulated for about one hundred years, from about the 990s to around 1105.
