In my opinion, any collectors who has been visiting Amcorp Mall Flea Market will surely visit Trigometric coin shop too. Trigometric Sdn Bhd or also know as "K.N Boon Shop" founded in 2002 specializes solely in dealing with World Stamps, Coins, and Banknotes. They're collecting and selling all kinds of different stamps, coins, and collectible currencies. Most of you maybe already own 5th edition K.N Boon Book, one of the must have book for Malaysian collectors. Trigometric also known for promoting cultural hobby and collections for youth and student with their KL International Money Fair 2001, 2003 & 2004 at PWTC. Its been to long since the last KL Money fair, hopefully we can see it in a near future.

Even though K.N Boon Shop is not that big but once you visit the shop, you feel like visiting a museum. All the banknote are neatly displayed on the wall, make you feel like the banknotes and coins are special. The shop open from Tuesday until Sunday from 10.00am until 7.00pm. The cheapest way to go there is using Putra LRT; Stop at station Taman Jaya, 5 minutes walk across the road to Amcorp mall. If you don't know which one is the Amcorp Mall building, you can always asked people there, many Malaysian are willing to help guiding you to that place.
Some of my readers asked me to take photo of KN Boon in 2010, I successfully take his photo but I respect his decision not to share his pictures online. By the way, the guy that you always meet at the shop is not K.N Boon.
Trigometric Sdn Bhd is one of the must visit coin dealer shop in Malaysia.
