mexican peso conversion to us currency?

Question

i want to know how much a 1991 10,000 mexican peso is worth now in the U.S

Answer 1

In January 1993, Mexico remonetized and 1000 old pesos became 1 new peso.
Your banknote is equal to 10 new pesos, which is about 90 cents US. It is probably worth more than face value as a collectible.
