What was the Mexican Peso to U.S. Dollar exchange rate on December 31, 1992?

Answer 1

If I remember correctly, it was about 3300 / US$1. Of course, that became 3.30 / US$1 when Mexico remonetized on 1 January 1993.

Added later: My memory is pretty good. According to the web site referenced below, it was 3121 / US$1
