Filled-Die Minting Error?

No, that one looks like someone altered it. Is it gray in color? What does the reverse look like? Looks like a pretty abused coin. I can see the 19 in the date and the central profile. But it is not a mint error.

Is the coin actually gray in color or copper colored? Looking at the rim of the coin it looks like it was placed in acid. for a time. If it is gray it could be a 1982-1999 zinc cent. If it is copper color without the reverse devices that might be a wide range it could be. But the way it might have been altered was to paint something on the obverse to keep the acid from removing the area we can see, then dipped into acid and it removed the plating, devices, but could not the area where it was painted. Then remove the paint and and you have what may have happened to your coin. The area at 8:00 makes me think it was a zinc planchet as that area looks really disturbed dissolving the zinc core?

Thanks, Richard. (and thanks John1 for teaching me a new coin-collector acronym).

The back is most certainly copper in color. I wish I could post a picture in this reply, but not sure how.

I'm pretty sure the front is copper in appearance (I'm colorblind, and a novice, so I can't answer confidently). The areas that look light gray in this photo are actually bluish.

More importantly, the "eroded edge" at 8:00 is an artifact of my attempt to improve the sharpness of the image. The edges are entire and smooth. (i. e., changing contrast made it appear that the edge was dissolved.)
