CM09 MEDAL OF NORODOM I
  Médaille de Norodom Ier
two (three?) classes - established ? (crowned June 3, 1864 – died April 24, 1904)
  For: service to the person of the king
  Design: round breast badge, gold/silver(/bronze?), 34mm across, with suspension ribbon
    Obverse: in center royal arms, and around the edge inscription in Western script "SOMDACH PREAH NORODOM PREACH CHAU CRUNG * CAMPUCHEA *";
    Reverse: inscription "NORODOM 1ER ROI DU CAMBODGE", with half suns with rays at top and bottom, and wreath on left of oak and on right of laurel all around edge;
    Suspension: a western style royal crown
  Ribbon: 36mm; azure 12mm, yellow 12mm, red 12mm
    As with some other medals in Indochina, recipients would sometimes mount the ribbon on the medal in reverse pattern.

The Medals of the Reign (Médaille du Règne / Meday Rochkal), were instituted only for the period of the individual monarch, and lapsed thus at the end of his reign. This first Reign medal, of Norodom I, has both a western crown and western script, along with a suspension from a Western style crown. This was changed with the subsequent Reign medals to the traditional Khmer crown as the suspension to the medal, and to Khmer script on the obverse. The various reign medals otherwise closely resemble each other.

The Medal of Norodom I was awarded in gold and silver. A bronze medal was also apparently awarded without a suspension and ribbon to lower ranking people who would not be expected to wear medals. Apparently some bronze medals, however, were worn, and were fitted either for bestowal or by the recipient with the suspension and ribbon.

They all appear French made, the gold class in gilt reportedly being manufactured by La Monnaie de Paris.

The medal is infrequently on the market.
