Section 2--724. Admissibility of Market Quotations.

Whenever the prevailing price or value of any goods regularly bought
and sold in any established commodity market is in issue, reports in
official publications or trade journals or in newspapers or periodicals
of general circulation published as the reports of such market shall be
admissible in evidence. The circumstances of the preparation of such a
report may be shown to affect its weight but not its admissibility.
