Brunei $100 Note

Someone in one of the banks gave me a call and said that he had in his hand the $100 bill Brunei second series. I told him to hold on to it and today I wanted to get it off him. That was when he told me he had four of them and the numbers are in a sequence. That probably will make them worth more in the future.This $100 was the second series produced for Brunei. The notes were printed in 8
