Title 11, Chapter 2, Section 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.
