HC Deb 12 May 1964 vol 695 c36W
32. Mr. Sorensen

asked the Postmaster-General what is the estimated number of foreign coins and metal discs annually used fraudulently in telephone coin boxes; and what is the estimated financial loss from this malpractice.

Mr. Bevins

I cannot give exact numbers, but the estimated loss is about £3,000 a year or 6d. per £100 of coin box revenue.
