ScottO Posted February 6, 2011 Report Share Posted February 6, 2011 was testing my chinese 3 cash from the northen sung (1086-1100) with a magnetic screwdriver (had to repair comp) and tested it against some more recent iron pieces (german notsgeld etc) and noticed that the german stuff stuck to the magnet, however the cash coin had very little pull whatsover (it was slight but hardly any movement towards it) and i know that magnetism fades over time, so is this a good test to do for authentic age?
