Compare it with a steel cent. That will tell you about how attracted it is to a magnet.

The pictures I uploaded do not show that the coin is shiny like a si;ver coin. Also the magnet pull is less than that of a 1943 steel penny. Approximately half that but yet enough to make it jump fully to a magnet from 1/4" away. the weight is 2.55 g.

The coin is uniform as to how is draws to magnet. aoo surfaces seem to be the same front back and sides. I measured more accurately and it jumps off the table and onto the magnet from about 1/2" away. I originally posted 1/4". the circumference of the edge of the coin is smooth.

There is NO WAY the Mint made a steel cent in 1987.

I measured the coin and it is .060-.061 thick and .750 in diameter. the physical weight and size is the same as other pennies of this period.

OK, I'm stumped. The only metals I can think of that would cause a cent to jump a half inch to a magnet are pure nickel or an iron alloy. The coin is the same size as a cent so it is too light to be nickel (A specific gravity test would confirm that) but it would be reasonable for an iron alloy. A pure nickel plating heavy enough to allow it to jump that far I would expect to be so heavy there would be detail loss. I'm not sure if even a large rare earth magnet would cause a plated coin with an average thickness plating to jump that far.

I saw the video. That coin has to be some form of iron (steel) or pure nickel. The earlier pics look like a genuine (or very close) coin. I'm certainly intrigued.

I am beginning to think of a "Mint-assisted" error in this case.
