All genuine 1977 cents were struck in bronze, which is not magnetic.
If your coin sticks to a magnet it has either been plated with enough nickel or other magnetic metal to stick, or it was struck in a different metal altogether.
If it's a different metal, you either have a fantasy piece someone made privately, or possibly an error that's called an off-metal strike. That error occurs when a blank for a foreign coin accidentally gets mixed in with normal blanks at the Mint. Off-metal strikes can be worth a premium, but you'd need to have your coin inspected by a professional coin dealer or grader in order to tell if you have a true error, a fake, or just an altered coin.

Do dull silver surfaces emit the same amount of radiation as shiny white surfaces?
Dull silver surfaces and shiny white surfaces can have different emissivity values, which means they might not emit the same amount of thermal radiation. Emissivity is a property that quantifies how effectively an object emits thermal radiation compared to a perfect blackbody at the same temperature. A blackbody has an emissivity of 1, and objects with emissivity closer to 1 are better emitters of thermal radiation. Dull surfaces, including dull silver surfaces, typically have higher emissivity compared to shiny surfaces. Shiny surfaces often have lower emissivity because their smooth and reflective nature reduces their ability to emit thermal radiation effectively. White surfaces can vary in terms of their shininess and emissivity. A shiny white surface might have a lower emissivity, while a more matte or dull white surface may have a higher emissivity. Therefore, if the dull silver surface has a higher emissivity compared to the shiny white surface, it will emit more thermal radiation than the shiny white surface at the same temperature. However, it's important to note that the exact emissivity values can vary based on the specific properties and conditions of the surfaces, so it's best to refer to specific emissivity measurements for accurate comparisons.
