Except
Die Deterioration will not show notching like this--it will be completely connected as the letter wears away on the die.
For example, the notched bottoms of the "M" and "T" are classic places for a doubled die--nothing else can produce that.
Depending how a die is made, the doubling can look somewhat different between countries/mints--which ads to the confusion.
That's why I look for notching such as above--there is no doubt to me.
