1. Question mark
At first, in Latin, to indicate a question, one must write the word "Questio" at the end of the sentence to indicate that the sentence is the sentence asked. So to save space, the word is eventually abbreviated to Qo, which is then compressed again into the small letters above the letter q o, which eventually grew out into dots and dashes like a worm, just like a question mark us now.
2. Exclamation mark

" or translated: "I will use this sign as usual, a pair of parallel lines, or a twin of equal length, because no two things could be more similar to these two parallel lines." Signs similar to the original findings of Robert least 5 times longer than we know today.

6. Dollar sign ($ symbol)
The U.S. government just issued their own money in 1794, and at that time was still using old-world currency - pesos - or Dollar Spanish. 1 Dollar coin exactly once as the first American Spanish pesos, both weight and value, so they take the same abbreviations: Ps.
