Hello all,
The trade in Malaysian medals here normally takes place between individuals, as the sale of medals and other awards to the public is prohibited by law. There are many reasons behind this, including the fact that certain awards, such as the Panglima Mangku Negara and Panglima Jasa Negara, carry with them titles (Tan Sri and Datuk respectively) and certain benefits.
However, Malaysian medals and awards do make it into the market, usually when the person who earned them passes away (or goes broke and needs money). I've seen an entire bar of British medals awarded to a Malayan soldier in the 50s sold to a collector by the grandson, but usually its individual pieces that hit the market.
Best place to look for these would be sunday markets (the most well-known is Amcorp Mall in Petlaing Jaya; markets are open saturday and sunday). There's individuals, traders and shops selling medals from Malaya, Malaysia and other countries in that place. I've seen colonial era medals (British, state), Malayan era (Federal, state, British awarded to Malayans), and Malaysian era on sale. Just the other weekend a lovely Sarawak set was sold (PNBS, which bears title 'Datuk Sri'), complete in presentation case. Another fellow turned up with a PMN (very high ranking Federal award which bears the title 'Tan Sri'), complete in case, which is something I'd not seen available before.
However, Malaysian medals are not cheap. My fellow countrymen are rather mercenary and know that these items are scarce. For example, the prices for the two awards mentioned above were MYR1,800 and MYR2,500 respectively (about USD600 and USD850).
My first post in GMIC btw!
