  Even though they're extremely easy to come by and grade isn't really that important, I'm wondering if they grade the same way as copper pennies even though they are made of a harder material. Also, what's the best color to use as a background for an auto-adjusting camera?

Black is the best color to use but I have seen people use red as well. And yes they grade all the pennies the same its not by what they are made out of, its what they are.

Steel cents are graded exactly the same as others. The best background to use is WHITE. Not only does it allow for proper white balance correction, it permits the viewer to mentally adjust based on the look of the white.

I tried to do the same coin on black just now and it came out over exposed. I'm sure it's steel because it's magnetic too.

You use a white background to ensure your White Balance is correct. After that, it hurts contrast by reflecting excess light back into the lens. Use black or grey once you have your particular White Balance needs figured out; if you don't change your lighting you don't need to touch White Balance for a different coin.
These images look as if the White Balance preset doesn't match the color of the light used. What kind of lighting? It's rare that a camera gets incandescent light this wrong on Auto.

It's an incandescent desk lamp, the background isn't perfectly white though

With a color background we can't help with color correction because we'll never actually know what that color is. An incandescent light should be an easy correction, so I'm guessing what you've seeing of your background is the right hue but a bit dark-looking, and the coin's color is close to reality. Except it's a Steelie, and can't be that color, so we're back to square one.  |

For most coins I use a tan background but some silver coins require a darker background. The biggest thing is to experiment with your camera/phone, lighting and background. You can take good pics with a bad camera. You can also take bad pics with a good camera, it all depends on lighting and contrast.
