@Rick pechia I see your Cent.. It's not steel. It is plated. Also.. You should create your own new separate thread in the future.
...I think I got it. They have a bitcoin that weighs 2.6 g and is magnetic. This would be a token, usually gold or silver plated.
It's chrome paint, and yes it sticks to magnets... Rustoleum still makes this stuff, "chrome paint". I'm thinking of plastering some painted pennies in a plaque I made, made to look like Elvis, some day.
This is an old thread and the answer is no it is not silver, no it’s not aluminum, no it’s not anything except a cent, probably altered.
Just a bit of historical information. Using coins in High School Science Labs was common to introduce the electroplating process using the copper cent because of it's electrical properties. It was attached to a battery and submerged in a solution containing another metal. Usually some form of nickel because it was inexpensive and contrasted starkly with the copper color. The solution was also attached to another piece of metal. Anode, Cathode and electrolytes were pretty standard science Experiments and Projects in the fifties and sixties. After the experiments were completed, the coins were often saved briefly until being spent. https://en.wikipedia.org/wiki/Electroplating
We also put cents in sulfuric acid and let them dissolve to different degrees. If you let it go long enough, only Lincoln's bust will remain. I still have mine somewhere from all those many years ago.
When a thread such as this comes up, the first question should be what kind and size of magnet is it? A neodymium ( Rare earth) composite magnet can be multiple times stronger than a similar Iron magnet. So a heavy coat of nickel on a copper cent can barely be lifted (if at all ) by a Iron composite magnet generally about 25% of the strength, but the similar size rare earth magnet should support it to some extent. The old "attracted to the magnet " as a real test was dumped when the rare earth magnets became available in the 70s and the newer combinations in the 80s. Jim
