Police have warned there is a “noticeable amount” of counterfeit Bermuda currency currently in circulation.The issue is particularly affecting $100 and $50 notes, a police spokesman said yesterday.“Local merchants in particular are once again reminded to ensure that their employees are aware of the importance of taking a few seconds to scrutinise the money they are taking in, especially the larger denominations,” he said.“If counterfeit cash is detected during a transaction, staff receiving the fake money should hold on to it, note the description of the individual who tendered it and contact police immediately.”The public was also warned to remain vigilant.“The counterfeit Bermuda notes currently being passed are the older notes not the new ones,” advised the spokesman. “To distinguish a genuine Bermuda note from a fake one, look for the tuna fish watermark to the left of the note, the metallic security thread just right of the tuna fish watermark and the silver ship to the right of the note.“Also, examine the paper quality, and check to see if the ink runs. Most counterfeit in circulation is being generated on ink jet printers, and the ink will run if it gets wet. Genuine currency will not do this.”He reminded the public that it is a criminal offence to make, possess, pass on or reproduce counterfeit currency, and the punishment is up to five years in prison.
