Hang on to any of the new Newfoundland quarters. If you have them, they may be worth much more than 25 cents.The Canadian Mint announced today that it is recalling all of the Newfoundland quarters that are part of its program featuring quarters from each province. "We are recalling all the new Newfoundland quarters that were recently issued," Canadian Mint Deputy Minister Jack Shackleford said Monday. "This action is being taken after numerous reports that new quarters will not work in parking meters, toll booths, vending machines, pay phones, or other coin-operated devices." The quarters were issued in the order in which the various provinces joined Confederation. and have been a tremendous success among coin collectors worldwide. "The problem lies in the unique design of the Newfoundland quarter, which was created by a team of Newfoundlanders," Shackleford said. "Apparently, the duct tape holding the two dimes and the nickel together keeps jamming the coin-operated devices."
