That feathery quality to the doubling in the first pics suggests Die Deterioration. You can see the die surface flow lines in the flat fields, moving in the same direction as the letter doubling. Machine Doubling like push doubling or slide doubling will steal metal from the devices, and tends to stand up from the fields much more sharply. In general, MD is subtractive from the parent device, and DDD is additive to the parent device (i.e. the parent device or letter is not diminished by the DDD because it has not donated metal to produce the doubling).
DDD is quite common on recent modern coins from Denver. It happens on Philly coins, too, but for whatever reason, can be really pronounced on Denver strikes.
