There were only two 1819 coins minted with that exact inscription. The 1819 Crown (Five Shillings) with the Regnal date of LIX (in Roman numerals) along the edge and the 1819 Crown (Five Shillings) with the Regnal date of LX (in Roman numerals) along the edge.
These were amongst the first Crown coins to be minted after the Recoinage act and were minted to the new standard of .925 fine silver, weighed 28.2759 grams and were 37.6mm in diameter.
Some of the coins with the LX Regnal date, were minted without a fullstop after TUTAMEN.
The reverse features Benedetto Pistrucci's St. George and the dragon in what could almost be called a cartwheel design.
The inscription around the reverse is "HONI SOIT QUI MAL Y PENSE" meaning "Evil to him who thinks evil".
The 1818 to 1820 Crown coins were the first to have been minted since 1751, and were also made from silver equal to less than the face value of the coin for the first time.
