"Not one" or "none", What's the Difference?

Not one or none? What are the differences between these two expressions below?

None penny more.
not one penny more

First, it is observed that the two terms sound similar in terms of pronunciation, however, they belong different word classes and must be used in different contexts to convey the meaning wanted.

'None' (all together) takes on the class of determining it's from Indefinite Pronouns of the Portuguese language and its meaning refers to the synonyms: any, nothing, nobody, or even to the antonyms: some (a) or someone, in a way that refers to magnitudes and quantities and demonstrates the non-existence of something or someone, according to the examples below:
This does not generate none problem.
None man has come this far.

While 'not one' (separate) is an expression composed by joining the adverb or conjunction 'nor', plus the number 'one'. Its meaning refers to the sense of not a single one, not even one, not even one. Note the examples:

It does not have not one bread for me to eat?
I don't have not one real to leave today.

Therefore, when doubts arise as to the use of these expressions, it is good to test by substituting the term for its antonyms and synonyms to check which one will fit correctly in the expected context, so you will be prepared to produce great texts and excel in the tests of Portuguese.
