HC Deb 09 December 1980 vol 995 c347W
Mr. Wheeler

asked the Chancellor of the Exchequer if he will list in the Official Report details of the market research into the currency and coinage requirements of commerce and the general public carried out by his Department or the Royal Mint over the past five years.

Mr. Lawson

No. The market research has been carried out by the Royal Mint and not the Treasury and much of it provides a basis for commercial decisions or confidential advice to Ministers.
