100 old pesos is worth about 1 USD cent. Any staement saying I will pay you ___ pesos is equivalent to saying old pesos unless mentioned new pesos equivalent 7 USD Dollars.
Well, 100 (Mexican) peso bill would be worth... 100 Mexican pesos (which is the currency they use in Mexico!) assuming it was after 1993, if the bill was before 1993 it would be worth 1/10th of a Mexican peso (since the New Peso was introduced in 1993 which 1 new peso is equal to 1000 old pesos)
It depends how old, but if it is from the issue before devaluation, then it is worth 0.1 New Pesos - or less than 1 US Cent.
Roughly it is worth at $73 for 1000 Mexican Pesos.
100 new pesos=$9.3217 American dollars 100 old pesos (before 1992) = slightly less than 1 cent.
If the coins are dated 1993 or later, 1000 pesos would be worth about $100 at current exchange rates. If the coins are dated before 1993, they are so-called "old pesos" worth 1/1000 of current pesos, so they would be worth all of a dime. HOPE THIS HELPS!!
You have what is known as an "old pesos" coin. In January 1993, the Mexican government introduced the new peso, worth 1,000 of the old pesos and divided into 100 centavos, to simplify foreign exchange. Current exchange rates are based on these "new pesos". Your old pesos coin has become essentially worthless for exchange. And there were far too many of them minted to be considered a collectors item. You'll find them in coin dealer miscellaneous foreign coin bins for 5/$1.00
20000 Pesos is worth about $1,858 USD However, if you have a coin or bill of this denomination, it is probably in "old pesos". It takes 1000 old pesos to equal 1 new peso, so the actual exchange rate is $1.85. [Note - there are some 8 countries using currencies called pesos. This answer probably refers to the Mexican peso.]
I assume this is a Mexican coin minted before 1993. If that's the case, it's denominated in what are called "old pesos" which were converted to new pesos at the rate of 1000 old = 1 new. The current exchange rate is about 10 U.S. cents to the peso, so your coin is worth about a dime.
I am assuming it is a 10 peso coin (shown as $10; "$" means "peso" on Mexican coins). If it's from circulation its value is quite low. Mexico's currency was devalued by inflation in the 1980s and the country replaced its money in 1993 at the rate of 1000 old pesos to 1 new peso. 10 old pesos would convert to 1/100 of a new peso, or much less than one U.S. cent at current exchange rates.
Mexico revalued its currency in 1992 due to severe inflation. "New pesos" were issued to replace the then-current ones at a rate of 1000 to 1, so your 20,000 old-peso note translates to 20 modern pesos, or about $1.50 as of 10/2009.
Nothing. The peso had changed in Mexico, making all the older pesos worthless. There was a time period where you could exchange your old pesos for the new pesos, after that you were stuck with the old pesos.
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.
