Well
DDD is seen on Single squeeze die coins. This is way before this
DDD area. This is just extreme die wear. Note the devices are moving towards the rim of the coin. After a few hundred thousand more strike, the devices will reach the rim:

Just like the die that struck this coin. Not a doubled die, but a normal die, with exreme die wear.
DDD as I mentioned is seen on the New die processes and affects the fields, not the devices. On the Pre-Single squeeze coins, the die wear affected the devices that face the rim. When the die ages a lot, then the devices will start their march towards the rim over the fields. Both are extreme die wear. But on
DDD, they fields are the first devices affected, then the
Ridge Ring appears. Then die polishing to remove the
Ridge Ring and the the fields start of reduce on the Liberty area. During all of this, the fields are affected. (devices are only affected by the die polishing to remove the
Ridge Ring) Why does it happen this way? Well with the higher profile on the older style dies and the lower profiles of the single squeeze dies, they are affected differently. Hope this helps.
Beginning of DDD? What is that? 4 stage aging process for the dies having
DDDhttp://goccf.com/t/429991#3695092 CoopHome:
Can DDD be seen on pre Single Squeeze Dies? the die wear is common on both, but the fields are affected on the Single squeeze dies first and not the devices. On the higher profile coins, the devices that face the rim move towards the rim.
