@jmart, if you are asking why they are different despite having similar metal alloys and mintage years, well then that is because they likely all were exposed to different environments over the years--some may have been buried in slightly acidic soil, others in water fountains. The one in your first pic that has a crescent-shaped tone on the rev most likely spent a bunch of time with another half lying partway obscuring it. We see that same patch of reduced toning when coins have glue or adhesive tape left on them for years.

Environmental Damage has caused them to tone like this.

Just exposure to unknown environmental conditions. Please show your images right-side up - this is important.

The oils from holding them in your hands/fingers doesn't help with the environmental effects. You may think it doesn't matter, but it does. Perhaps this coin doesn't matter, but it's best to get in the habit of wearing cotton gloves, just fyi.

More of a staining of the coin. Tossed into a drawer and left for years. Something affected the coin. (blame it on neglect)
