Copper and manganese are not normally magnetic. However, a ground-breaking new technique, developed by Oscar Cespedes of the University of Leeds, UK, has transformed copper and manganese into magnets, structures called Buckyballs. This alloy it is use also in wind turbine and many others applications. If this alloy was use, the weight will be more then that a normal cooper alloy use for coins and it is 10% magnetic. Another possibility it is an cooper 90 nickel 10 which make the alloy been magnetic. For the point of view of plating, is no questions to be thick. To be thick we go to others coating processes, like plasma or laser.

the Rim Above liberty showing steel Planchette Your wheatie is NOT a steel planchet, it is simply a normal but plated copper cent. There are several metals that it could be plated with and be magnetic as well. Being a normal but plated cent means it is simply post mint damage. Value: one cent. And btw, you CAN type more than one sentence into a message; no need to type each one and post it by itself.

Probably way off base into the realm of improbable . . but . . Consider the possibility of someone taking a '43 steel cent, removing the date, restriking it as a '55s and plating it. If you look at an actual '55s date it's different.  |

I don't know where you get your sources, but that is not what "buckyballs" are; their proper name is Buckminsterfullerene, which is a type of fullerene with 60 Carbon atoms. Each Carbon has three bonds and it has a cage-like fused-ring structure (truncated icosahedron) that resembles a soccer ball.

I will send you by e-mail. This new alloy is magnetic only 10%, but magnetic.
