I have a 1984 quarter that is smaller in diameter, thicker, weighs only 4.1 grams, and is not attracted to a magnet. I have been told that it may be on a blank that was intended for a 50 poisha coin of Bangladesh which were struck at the RCM in 1984. It needs to be examined by an XRF machine to be sure. Does anyone know who might have one in southwestern Ontario?
