ما هي العملات التي يصدرها بنك الكويت المركزي؟

Could you elaborate on the currency system in Kuwait, specifically highlighting which coins are issued by the Central Bank of Kuwait? I'm curious to understand the denominations and any unique features that may be present in the country's coinage. Are there any commemorative coins or special editions that are released periodically? Additionally, is there a history behind the design and issuance of these coins that one should be aware of? Your insights would be greatly appreciated.
