Mexico revalued its currency in 1992-93 due to hyperinflation. "Nuevo pesos" (new pesos) were introduced at the rate of 1 nuevo peso = 1000 old pesos.
That means a coin dated before 1992 is worth only 1/1000 as many current pesos; i.e. an old 1000-peso coin is only 1 new peso. At current (2009) exchange rates 1 new peso is worth less than a U.S. dime.
The nuevo peso (new peso) was the result of hyperinflation in Mexico.
In 1993, Presidente Carlos Salinas de Gortari stripped three zeros
from the peso, creating a $1 New Peso for $1000 of the old ones.
Today $1 is equal to 12-13 pesos.
If your peso looks like the one at the related link below, then it is worth between $1 and $4, depending on the market and potential buyer.
On average, one American dollar was valued at 310.28 Mexican pesos during 1985.
about 75 cents
When the switch was made to the Euro, 1000 lira (not dollars - it translates as pounds) was worth roughly 50 cents U.S.
The U.S. made no dollar coins in 1990.
a lot like 1,000 dollar
No, since re-valuation in 1992, the largest denomination Mexican Peso note is the 1,000 Peso. The 50,000 Peso note was last issued in Dec 1990 with an exchange value of 1:1000 with the new Peso (about $4). Mint condition 1990 notes are worth $45 to a collector. Used condition ones are worth about $6.
twenty dollars
In mint uncirculated condition, a 1990 $20 note is worth $30. In normal condition, it is worth exactly $20.
about 80+ bux This is not correct. The MXN (Mexican pesos) printed after 1993 are currently worth about 8 cents to the American dollar, so a 1000 peso note would be worth about 80 dollars. A 1988 1000 peso note, the MXP, is worth 1000 times LESS than that. The MXP is obsolete, worthless to anyone but a collector of older bills. Sorry, but I did the research for myself, to save time. I have 38k in pesos, but they are all notes/coins printed before 1990, so the value of $3000 USD I thought I had went down to about $38 USD. Don't be disappointed when you get to the bank, $38 will fill your gas tank, at least.
If this is asking the value of a 1990 half dollar, it's worth 50 cents.
Ah, 20 dollars.
10cents
