Authority yesterday.

The move follows the recent discovery of a forged $100 note on the Island -- similar to five counterfeits identified earlier.

Now the BMA have issued a checklist of key features to distinguish genuine $100 notes from fakes.

A spokesman for the BMA said the front of the note should have Bermuda Monetary Authority written in micro text beneath the denomination in the centre.

And the top right hand corner butterfly should change from purple to silver when the note is looked at slantwise, while a lead lining running from top to bottom of the note should have the word Bermuda running through it.

On the reverse of the note, the Bermuda coat of arms in the top left hand corner and a flower design on the right hand side should both be in fluorescent silver. There should also be a tuna fish water mark.

The spokesman said: "Conterfeits found to date do not have these features, are of a bolder orange colouring and are noticeably smaller than genuine notes.'' He added: "Anyone with a suspected counterfeit in their possession should draw it to the attention of the Bermuda Monetary Authority or take it to the nearest Police station.''
