Sorry to break it to you, but this coin is not silver, just silver plated. The real composition is Bronze. The value is pretty much gone because of this damage, but it would be worth around $4-$5 without any damage.
lovecoins: The "black spots" you see are actually places where the bronze underneath shows through.
