This guide will address only the DEUTSCH-NEUGUINEA 1912 clasp which was worn on the Kolonialdenkmünze. The Imperial German Colonial Medal (Kolonialdenkmünze or KDM) was established by Kaiser Wilhelm II on 13 June 1912 with revisions on 17 February 1914.  The medal with clasps was awarded retroactively.  The DEUTSCH-NEUGUINEA 1912 clasp was awarded for 2 Punitive Expeditions:

• June through November 1912:  Kagam Punitive Expedition in to the Tolukuma area of Papua, New Guinea.  Plantations and residents had been attacked by the Kagam and the Imperial german Colonial Government decided to punish those responsible by over 100 Police Troops.  There were casualties to both sides.  Troops who participated did not serve in the Zedu, Bemari, and Koipassin Punitive Expedition.
• June and July 1912:  Punitive Expedition in against the Zedu, Bemari, and Koipassin (in the Madang area of Papua New Guinea).  Plantations and residents had been attacked by the Zedu, Bemari and Koipassin and the Colonial Government decided to punish those responsible with over 100 Police Troops.  There were casualties to both sides.  Troops who participated did not serve in the Kagam Punitive Expedition.

DEUTSCH-NEUGUINEA 1912 Clasp

This clasp was awarded only to Imperial German Colonial Police Troops.  Approximately 200 men were authorized this clasp (in all categories) and possibly half received the  DEUTSCH-NEUGUINEA 1912 clasp in late-1912.  While the medal is somewhat rare, these bronze DEUTSCH-NEUGUINEA clasps are very rare.  Specialty collectors generally consider this clasp the most widely awarded but documentation does not clearly support this opinion.  As of 1 March 2007, this bronze clasp is only known in one officially issued type:  same width as the ribbon, wide lettering, flat back, pebbled background and with soldered sharp flat prong backs.  This is not to say that another type wasn't officially issued as well but that only this one type has been verified. 

• In 1997, a single clasp was offered in Germany for €125
• In 1999, a single clasp was sold in Germany for €118 
• In February 2003, a single clasp was offered at a German Militaria Show for €150 but was suspect.
