In 1989, production was transferred to the Continental Coin Company (in California). From 1989 to 1995, the mint produced various themed commemorative Hutt River Province coins which were sold on the US market. Although the total number of coins minted is unknown, it is known that 10,000 $20 coins were minted in 1991 to mark the 50th anniversary of the attack on Pearl Harbor. Up to 200 different commemorative coins in three denominations each ($5, $10 and $20) are believed to have been minted to commemorate Desert Storm, World War II, The Fathers of Baseball, etc. Prince Leonard authorised all these coins and received samples as well as royalties.
