The first image is showing a lot of what is called, 'Split plating.' When the plating is split, the zinc gets oxygen and starts to react rising. On this coin I feel the MD caused this split plating after the strike. So the last image in the open field may be a gas bubble under the plating. So a lot of stuff going on, but no premium for it. The countdown started to click down as soon as the split plating happened. So a very spendable coin that time will eventually cause to be erased from existing in the future. Spendable.
