Is the Brunei 50 cents 2002 very common or not?

Hello all!

The Brunei 50 cents 2002 appears readily available in Russia and other places at prices ranging from 2-3 Euros to over 8 Euros in conditions ranging from EF to UNC. The catalog on this site rates it at very common. 

However, only 1325 were minted, which appears very low in relation to the quantity minted for other dates of this type.

So what is the story? I have one original roll for sale that I obtained at the Monetary Authority building in BSB almost 20 years ago. Should I sell for US$ 150. Or hold on?

Views (intelligent!) please....
