Mexican currency is denominated in pesos rather than dollars, but they use the $ sign to indicate pesos, so it causes a lot of confusion.
You'll need to post a new question with your coin's date and a description of the image on it. The date is very important because Mexico changed the value of its currency in 1992-93. "Nuevo pesos" (new pesos) were issued to replace old ones at a 1-to-1000 exchange rate. That means if you have a coin worth 20 nuevo pesos, it would exchange for about two U.S. dollars. However, if it's old pesos, it would be worth only one-one thousandth as much - i.e. just two-tenths of a cent.
5*20 cents (Australian) make a dollar. In US and Canadian coins, a 50 cent piece, a quarter, two dimes, and a nickel also make a dollar.
I have a 20 dollar gold piece, st. gaudens, it has a (C) with an (A) in the middle under the date, nothing on top of the date.......
There are 20 nickels in a dollar, so one nickel is 1/20 of a dollar.
One half dollar (50 cent piece) and two quarter dollars (25 cent each piece)
