This is probably the most wanted of all Brunei stamps. Valued at five digit, not many can be found and many are fakes. I bought this a few weeks ago and it has just arrived. Honestly I am not even sure whether this is a fake or otherwise but judging by the price, it would not be an original. But if you do pay a lot higher how would you know it is not a fake? I have seen some of the authentication and I am not convinced either. So caveat emptor. Buy and pay at your own peril.
