$ WHAT DO YOU KNOW ABOUT GREEN NOTES IN YOUR WALLET? $ (ending)
While collecting the information for this topic I’ve found some theories of the Dollar Sign $ Origins.
As we know, the symbol of dollar is more recent than the name. And there are some theories about the origin of the dollar.
$ 1___The United States Abbreviation Theory
One of the most popular theories is that the dollar sign is derived from the initials of the United States. If you write a capital “U” on a capital “S” then drop the lower part of the “U”, you will get the dollar symbol with two strokes.
$ 2___The Peso Abbreviation
More widely accepted theory nowadays is that the sign comes from the Spanish peso.
One version of this theory is that the standard abbreviation of “peso” was simply “P”, but the plural form was a large “P” with a small “s” above it. This was simplified by leaving only the upward stroke of the “P”.
But if the peso abbreviation theory is the correct one why is the US dollar sign sometimes written with two vertical strokes? I don’t know the answer for this question. 
$ 3____The Shilling Abbreviation Theory
There is a view that the dollar symbol derives from the abbreviation for the shilling, which was used in Britain. A stroke through a letter was sometimes used to indicate that the letter was an abbreviation. The classic example of this is the British pound symbol £ the capital L with a stroke. The pound symbol is derived from the Latin word libra.
$ 4____The Slavery Theory
Some scientists suppose that the dollar symbol, $, is derived from the words for “slave” and “nail” in Spanish. The shackles worn by slaves could be locked by a nail which was passed through the rings or loops. The Spanish word for slave is esclavo and for “nail” is clavo. You can see it on the blackboard “S-clavo = esclavo”.
As for me, I think that the first theory is the best one. And which of these ones do you like?
