HC Deb 10 November 1958 vol 595 c21
31. Mr. Janner

asked the Minister of Pensions and National Insurance whether he is aware of the increasing extent to which stamped insurance cards are being stolen so that the used stamps can be removed and improperly applied to current cards; what estimate he has made of the current losses being suffered by the insurance funds on this account; and what remedial action it is proposed to take.

Mr. Boyd-Carpenter

My information does not suggest that thefts of stamped National Insurance cards are becoming more prevalent. The loss to the insurance funds from the affixing of used stamps cannot be precisely estimated but is believed to be very small in relation to the total sale of stamps. Methods of prevention and detection continue to be applied and developed.
