In total 5 pieces of certified specimen coins of Malaya And British North Borneo have been listed in Stack's Bowers Auction in coming April 2017 (Hong Kong session). In general, most of them are still retained in excellent luster and flawless appearance instead of relatively less in number according to well established population reports in market.
In my personal point of view, the auctioneer estimation is acceptable and well reflects its current value. No matter how, specimen coin collection is still a minor numismatic subject in the region of Malaysia and Singapore, how do you think about their results or future prospect?
