They all appear to be grease strikes. One easy way to distinguish a grease strike from a weak strike is to look at the edge. A grease strike...
I've always doubted both the spoon job and clothes dryer hypotheses because neither the edge nor the coin's surface ever shows percussion marks....
Damaged outside the Mint.
