While it looks like it is just starting to show
DDD, it is actually a die that was polished and removing the first stage of the
DDD:

Note the size of the devices, they are reduced in size. So the die on stage 2 will start to form the
Ridge Ring stage. So it is advancing in die age. When the
Ridge Ring forms it will look like this:
Stage 1:Field distortion towards the closest rim directions:
Stage 2: Ridge Ring
When that is removed, the next step of die polishing will weaken the devices a lot more.
Stage 3: Extreme Die Polishing:
Stage 4: Will show a distortion on the fields:

All parts of the aging process. Not a plus for these examples. But to help during your searches, know what is going on, trains your eyes, so you can move on to the next coin.
Is there a Stage 5? So far it hasn't been revealed yet to me. (This process so far is noted more on cents) But I feel it also affects other dies as well.

DDD? What is that? stages of die aging. not a premium for the coins, just what is going on with these single squeezed dies with the lower profiles.
