the “d” is filled completely in. The “In” in god trust run together. On the reverse side, the “M” in UNUM is hard to see, also these letters are close really together. The “A” in America and dollar are filled in as well.. are these errors?
The D Mint Mark could be filled in. Small Die Chip. Nothing really major. Everything else is a result of circulation wear.
May be a die crack coming from the rim through the "R" in DOLLAR. Or damage looking at the impression on the rim.
