I know it was between 1997 and 2002, but when were specifically (date) put on sale the first and last single issues?
Of the main series, the first issue has a cover date of September 1997 and the last issue has a cover date of November 2002.
So July 1997 - September 2002 with the two month discrepancy.
On Comic Vine, issue #1 is marked September 1, 1997, and issue #60 November 1, 2002, but that is likely incorrect.
